Cell Respiration Flashcard

Front

What is the purpose of cell respiration?

Back

The purpose of cell respiration is to produce usable energy in the form of ATP.

Front

How is energy released from ATP?

Back

Energy is released from ATP by removing the 3rd phosphate group.

Front

Which structures make up the ADP molecule?

Back

ADP is made up of two phosphate groups and one ribose sugar.

Front

Is ADP or ATP more like a fully charged battery, and why?

Back

ATP is more like a fully charged battery because it has three phosphate groups; breaking and reforming the bonds among them releases energy.

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondria.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, used to store and transfer energy.

Front

What is the role of mitochondria in cell respiration?

Back

Mitochondria are the organelles where cell respiration occurs, producing ATP through the Krebs Cycle and oxidative phosphorylation.

Front

What is glycolysis?

Back

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

Front

What are the end products of the Krebs Cycle?

Back

The end products of the Krebs Cycle are carbon dioxide, ATP, NADH, and FADH2.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
