How is ATP made from glucose?

Answers

Glucose is converted into ATP by cellular respiration.During glycolysis, a glucose molecule with six carbon atoms is converted into two molecules of pyruvate, each of which contains three carbon atoms.

The metabolic process known as cellular respiration, which takes place inside of cells, releases energy and waste products by converting biochemical energy from meals into the chemical compound adenosine triphosphate (ATP).

Cellular respiration transforms glucose into ATP.The aerobic respiration of one glucose molecule in the cytoplasm and mitochondria results in the production of 38 ATP molecules.

Glycolysis, the Krebs cycle, and oxidative phosphorylation are processes that take place during cellular respiration.

Two molecules of pyruvate, each having three carbon atoms, are produced during glycolysis from a single glucose molecule with six carbon atoms. Two molecules of ATP are hydrolyzed to give energy for the initial stages for every molecule of glucose, but four molecules of ATP are created in the later processes.

What statement best describes why the process of meiosis is important to Mendel's law of independent assortment of traits on different chromosomes?

Answers

The correct answer (B) In a "fair meiosis", there is an equal probability of each allele going to the gametes.

Independent Assortment Experiment by Mendel

In plants that were true-breeding for two characteristics, Mendel conducted dihybrid crosses. For instance, a plant with round seeds and the color of yellow seeds crossed pollinated with a plant with wrinkled seeds and the color of green seeds.

Round seed shape (RR) and yellow seed color (YY) characteristics are prevalent in this hybrid. Recessive traits include wrinkled seed shape (rr) and green seed color (yy).

The kids that resulted (or F1 generation) were all heterozygous for yellow seeds and spherical seed morphology (RrYy). This indicates that in the F1 generation, the dominant features of spherical seed shape and yellow color totally concealed the recessive traits.

Full Question: What statement best describes why the process of meiosis is important to Mendel's law of independent assortment of traits on different chromosomes?

Meiosis provides a way for alleles to maintain the associations they had in the parental generation.

In a "fair meiosis", there is an equal probability of each allele going to the gametes.

In meiosis, the segregation of one pair of homologous chromosomes affects the segregation patterns of other pairs.

Homologous pairs of chromosomes line up at the metaphase plate in meiosis.

In meiosis, how each pair of homologous chromosomes segregates is unaffected by what other pairs do.

Cellular Communication and the Cell Cycle FRQ:

a) Low extracellular pH activates TRPV1 through the binding of H + ions to TRPV1. Describe the properties, including the location, of the site of TRPV1 that allow H+ ions to bind. Describe the specific location in the cell where ATF3 protein is produced.

b) The pGoG protein is known to block the G1 to S transition in the cell cycle. Explain why this prevents mitosis from happening in the cell

Answers

Specifically, in sensory neurons, the plasma membrane of cells contains the cation channel protein TRPV1. Heat and low extracellular pH are only two of the many triggers that might cause it to become active.

The protein TRPV1 undergoes a conformational shift in response to the adsorption of H+ ions, opening the ion channel and allowing calcium ions to enter the cell. The subsequent signaling pathways that result in the perception of pain are activated by this calcium ion inflow.

ATF3 protein is exclusively synthesized in the cytoplasm of the cell, more particularly in the nucleus, where it is transcribed from the ATF3 gene.

The pGoG protein is known to block the G1 to S transition in the cell cycle by inhibiting the activity of the cyclin-dependent kinase (CDK) that is responsible for initiating DNA replication. This prevents mitosis from happening in the cell because, without DNA replication, the cell cannot divide.

Additionally, the pGoG protein also promotes the activity of the tumor protein p53 which is also known as the "guardian of the genome" and helps to prevent DNA damage and cell mutations, when it is activated it can stop the cell cycle and prevent mitosis from happening.

Humans rely on sensory receptors to interpret messages about their surroundings. Sensory receptors respond to mechanical, physical, or chemical stimuli. There are different kinds of sensory receptors for detecting different kinds of stimuli. Chemoreceptors are specialized nerve cells that pick up chemical stimuli, such as smells or the pH level of foods. Such stimuli tell the brain and body to react a certain way to protect the body. If a person in a controlled test is introduced to a safe chemical stimulus, what is the most logical prediction you could make?

A. The person will bat the eyelids to push the chemicals away with the eyelashes.

B. The person will plug the nose to shield the body from offensive chemical smells.

C. The person will cover the ears to protect the ears from chemicals in loud noises.

D. The person will bite the nails to keep the chemical from seeping into the fingers

Answers

The most logical prediction you could make is the person will bat the eyelids to push the chemicals away with the eyelashes.

Internal organs as well as specialized organs like the eyes, ears, nose, and mouth include sensory receptors. Each receptor type transmits a unique sensory modality that eventually combines into a single perceptual frame.

Chemoreceptors are specialized nerve cells or receptors that detect changes in the chemical composition of the blood. The prefix "chemo-" alludes to the chemical makeup of the blood. The brain receives this data from the chemoreceptors to assist in maintaining the balance of the respiratory and cardiovascular systems.

They are proteins that detect and engage with particular chemicals known as ligands on the cell membranes.

A student reads in a newspaper that the soil in his area contains high levels of arsenic. Based on this information, he believes that his fellow high school classmates have this metal present in their bodies. To test his hypothesis, he conducts an investigation of the soil in his schoolyard to see if it is contaminated with arsenic. He tests seven different areas around the school and finds high levels of arsenic in each. He concludes that the students at the school must have high levels of arsenic in their systems as well. Which of these is the best evaluation of his conclusion?
A. His conclusion is valid because he tested enough areas of soil to validate his hypothesis.
B. His conclusion is flawed because he did not test the soil at the homes where the students lived.
C. His conclusion is valid because arsenic is a toxic metal and is easily absorbed by the human body.

Group of answer choices new individuals are added to the population as N approaches K the population growth rate slows dramatically as N approaches K new individuals are added to the population most rapidly at the beginning of the population's growth only density-dependent factors affect the rate of population growth carrying capacity is never reached

Answers

In the logistic population growth model, population growth slows dramatically as N approaches K.

There are various mathematical models that can explain population growth. In the exponential growth model, population size follows a “J” shaped curve and grows very quickly. In the logistic growth model, population size follows an “S” shaped curve, growing rapidly and then leveling off.

When the population size N is well below the carrying capacity K, the population size increases rapidly, forming the first loop in S. As N approaches K, resources are limited, population growth slows down, the curve levels off, and his second loop to form an 'S'.

If the resilience of a damaged ecosystem is low enough, the degraded area may not be restored by secondary succession. When this happens, the damaged ecosystem has reached ____.

Answers

A tipping point is the point of no return, when the damage to an ecosystem has been so great that it can no longer recover through natural processes, such as secondary succession.

The tipping point is typically reached when the resilience of the ecosystem has been severely weakened, meaning that the system is unable to respond and recover to disturbances and disturbances can no longer be easily reversed. This can be due to a number of factors, such as climate change, pollution, overuse of resources, deforestation, and so on.

When the tipping point is reached, the ecosystem may never recover in its original state and may be permanently damaged or even destroyed.

Why do phospholipids tend to spontaneously orient themselves into something resembling a membrane?

Answers

The hydrophobic, nonpolar regions of Phospholipids must align with each other in order for the structure to have minimal potential energy and, consequently, higher stability.

Because their fatty acid tails are poorly soluble in water, phospholipids spontaneously form bilayers in aqueous solutions, with the hydrophobic tails buried in the interior of the membrane and the polar head groups exposed on both sides, in contact with water.

Phospholipids in the lipid bilayer of a cell membrane orient themselves so that the heads face outward because the heads containing the phosphate group are hydrophilic and the cytoplasm of the cell is an aqueous environment.
