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.

Answer:

The correct answer is

- Carbon dioxide, ATP, and NADPH,

- In the stroma of the chloroplast.

Explanation:

The product of the light-dependent reaction that uses in the Calvin cycle or the light independent cycle. Calvin cycle is the light independent cycle that involves the production of the glucose by converting carbon dioxide and other products of light reaction.

The light-independent reaction takes place in the stroma a fluid-filled region of the chloroplast in the photosynthetic organisms.

Thus, the correct answer is -
