How does cellular respiration differ from photosynthesis?

Back

Cellular respiration is the process of breaking down glucose to release energy, while photosynthesis is the process of converting light energy into chemical energy in the form of glucose.

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.

What occurs during the Krebs Cycle?

Back

During the Krebs Cycle, pyruvate is further broken down, producing carbon dioxide, ATP, NADH, and FADH2.

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration, where electrons are transferred through a series of proteins, leading to the production of a large amount of ATP.
