Cellular Respiration PZH

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondria.

Front

What happens in the electron transport chain?

Back

In the electron transport chain, NADH and FADH2 drop off hydrogens to form massive amounts of ATP.

Front

What happens to the carbon atoms in glucose during cellular respiration?

Back

The carbon atoms in glucose are exhaled as CO2.

Front

What are the outputs of glycolysis?

Back

The outputs of glycolysis include ATP and pyruvic acid (x2).

Front

Where is the energy in ATP stored?

Back

The energy in ATP is stored in the bond between the second and third phosphate.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

The three main stages of cellular respiration are glycolysis, the Krebs Cycle, and the electron transport chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.
