When oxygen is plentiful inside a skeletal muscle cell, what happens to the pyruvic acid that is formed during glycolysis?
Iteru [2.4K]

Answer:

d. it diffuses into mitochondria to be broken down to generate ATP

Explanation:

When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.

The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.

The use of personal protective equipment should always be imposed in doing potentially infectious work, especially in the hospital.

HELP! Me!
OLEGan [10]

Answer:

They camouflage

Explanation:

The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.

I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.
