"Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis"
PLEASE HELP!!
Answer:
Explanation:
The electron-carrier proteins are arranged in the inner mitochondrial wall. A dehydrogenase enzyme (think of it as the first protein of the electron-transport chain) oxidises NADH2 (which is the reduced coenzyme NAD) and/or FADH2 (reduced coenzyme FAD). The energy from the oxidation process is used to pump hydrogen ions from the matrix to the inter-membrane space of the mitochondrion. Because of this, gradient of hydrogen ion concentration builds up across the inner mitochondrial membrane, which generates a potential difference across the membrane. The protons then flow back to the matrix through an enzyme called ATP synthase (also called ATPase). (This is called chemiosmosis because a chemical substance (H+) moves across a membrane, down the concentration gradient.) This releases energy needed for the ATP synthase to phosphorylate ADP, i.e. make ATP (chemical energy for use in the cell) from ADP and inorganic phosphate.
Note: Bolded things are important, everything else is just additional clarification in case you need it. This is the last major phase of cellular respiration. If you want a deeper insight into the process, I suggest you read a bit about glycolysis and Krebs cycle.

What determines the type of feedback? A. How close to equilibrium the characteristic is B. How the body responds to a change C. How much product is present already
Answer:
The awnser is B
Explanation: no explanation
The fact that determines the type of feedback is "How the body responds to a change?" Thus, option B is correct.
What is positive feedback?A feedback has been known as the process where a system responds to an external or internal stimulus. There are two major types of feedback in a system, they are negative and positive feedback or we can say that there are two types of feedback is there one is positive feedback and another one is negative feedback.
Positive feedback is a type of response that occur when an output or response is an enhancement of the input. It's output moves further away from equilibrium. A negative feedback occur when a fraction of the output is fed back to the system to control fluctuation of other output.A feedback has been known as the process where a system responds to an external or internal stimulus.
Therefore, The fact that determines the type of feedback is "How the body responds to a change?" Thus, option B is correct.

Discuss the ways in which carbohydrate metabolic pathways, glycolysis, and the citric acid cycle interrelate with protein and lipid metabolic pathways
The ways in which the carbohydrate metabolic pathways, glycolysis and the citric acid cycle relate as they obtain energy for the body.
What is metabolic pathways?
Metabolic pathways is the set of chemical reactions that occur in cells that allow them to stay alive, grow and divide.
Glycolysis - oxidation of glucose to obtain ATPKrebs cycle - oxidation of acetyl-CoA in order to obtain energyOxidative phosphorylation - elimination of electrons released in the oxidation of glucose and acetyl-CoA. Much of the energy released in this process can be stored in the cell in the form of ATP.Pentose-phosphate pathway - synthesis of pentoses and obtaining reducing power for anabolic reactionsUrea cycle - elimination of NH4+ in less toxic formsβ-oxidation of fatty acids - transformation of fatty acids into acetyl-CoA, for later use by the Krebs cycle.Gluconeogenesis -synthesis of glucose from smaller molecules for further use by the brain.Whit this information, we can concclude that the ways in which the carbohydrate metabolic pathways, glycolysis and the citric acid cycle relate as they obtain energy for the body.

What is the half life of a radioactive isotope if a 500 gram sample decays to 62.5 grams in 99 years?
Answer:
24.75 years
Explanation:
62.5 is 1/4 of 500, which means that in 99 years it passed through four half-lifes. So, you divide 99 by four and you get that the half-life is 24.75 years. 25 years if it was rounded

During a Vo2max test, many people have a Respiratory Exchange Ratio greater than 1.0 as they approach their VO2max. Why
The important of RER between 0.7 and 1 shows a blend of carbohydrates and fat as a basis of energy. In case the value is more significant than 1, it means anaerobic respiration as a result of more carbon dioxide being developed than the oxygen that is being consumed.
What is the difference between vo2max and relative vo2max?Absolute VO2 max is only the amount of oxygen you breathe in liters per minute.
This dose depends on your age, weight, size, and gender. Relative VO2 maximum Relative VO2 max calculates your weight in liters per minute per kilogram of body weight.
Thus, anaerobic respiration results of more carbon dioxide being forged than the oxygen that is being destroyed.

Which is the next structure to contact air after it passes from the nose to the nasal cavity?
the pharynx
the larynx
the bronchus
the trachea
Answer:
the pharynx
Explanation:
edge 2022
The next structure to contact air after it passes from the nose to the nasal cavity is the pharynx.
What is pharynx?The pharynx is a muscular tube located behind the nasal cavity and mouth, connecting them to the esophagus and larynx. It serves as a shared pathway for both the respiratory and digestive systems.
In terms of the respiratory system, the pharynx plays a crucial role in the passage of air from the nasal cavity or mouth to the larynx. It acts as a conducting tube, allowing the air to flow smoothly towards the lower respiratory tract. The pharynx also houses the tonsils, which are part of the body's immune system and help protect against pathogens.
Additionally, the pharynx is involved in the process of swallowing. It facilitates the movement of food and liquid from the mouth to the esophagus, ensuring that they enter the digestive system and not the respiratory system.
Overall, the pharynx is a vital structure that serves as a passageway for both air and food, contributing to the proper functioning of the respiratory and digestive systems.
