When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
Lactic acid begins to build up during some exercises, such as running and swimming.
Some people don't build up lactic acid nearly as much, such as <span>Dean Karnazes, who once ran 50 miles in 50 days, then ran the 1300 miles back to the start.</span>
After the hydrolysis of ATP, the actin would then rebind to the myosin which causes it to release the phospate group of the ATP which is said to allow the myosin conformational change while it is bonded to actin. Hope this answers the question.
Answer:
b. His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
Explanation:
The formation of pyruvate from glucose occurs during the process of glycolysis. It occurs in the cytoplasm. Pyruvate must enter into the mitochondria so that it is decarboxylated into acetyl CoA to enter into the citric acid cycle. Following this, NADH and FADH2 formed during glycolysis and citric acid cycle are oxidized by electron transport chain and the resultant proton concentration gradient drives ATP synthesis.
The given animal lacks the protein that transports pyruvate across the outer mitochondrial membrane. Therefore, pyruvate can not enter into the citric acid cycle and the animal can not derive energy by aerobic respiration of glucose.
