How does energy from cellular respiration ultimately comes from the sun

Answers

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

"Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis"

PLEASE HELP!!

Answers

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.

Discuss the ways in which carbohydrate metabolic pathways, glycolysis, and the citric acid cycle interrelate with protein and lipid metabolic pathways

Answers

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.

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

Answers

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.

Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What was the result of depletion of the smelt population? Choose all that apply.
A) salmon populations declined
B) all three populations increased
C) all three populations would decrease
D) growth rates of both lake trout and salmon suffered
E) salmon population would decrease but the others would remain unchanged

Answers

Answer:A and D

Explanation: trust me don’t put c

What is the prey-predator relationship?

In an ecosystem, there are predators and prey. If the predator population grows, they will consume more prey more quickly, causing the prey population to decline rapidly. When there are more prey in an ecosystem, it would be advantageous for the predator, and after some time, the prey will decrease in number and the predator will increase.

Salmon, mouth bass, and lake trout feed on smelt in the lake. Lake trout populations increased in the late 1980s, and as a result, they began feeding on smelt. The other two predators were also affected. The salmon population declined for some time, but later their number increased too. The mouth bass population got affected a lot, and their number kept on declining. The other two species chose different prey and multiplied.

Hence, for some time, the salmon population declined. Option A is correct.
