Cell Respiration Flashcard

Front

What is the structure of an ADP molecule?

Back

ADP (Adenosine Diphosphate) consists of an adenine base, a ribose sugar, and two phosphate groups.

Front

Where does the Krebs Cycle occur in the cell?

Back

The Krebs Cycle takes place in the mitochondria.

Front

What must happen to the bonds in ATP to form ADP?

Back

The bonds between the second and third phosphate groups (C and D) must be broken.

Front

How is energy released from ATP?

Back

Energy is released from ATP by removing the third phosphate group.

Front

What is the waste energy produced from respiration?

Back

The waste energy from respiration is given off as heat.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP.

Front

What are the three main stages of cellular respiration?

Back

The three main stages 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 role do mitochondria play in cellular respiration?

Back

Mitochondria are the powerhouse of the cell where the Krebs Cycle and Electron Transport Chain occur.

Front

What is the significance of the Electron Transport Chain?

Back

The Electron Transport Chain is significant because it produces the majority of ATP during cellular respiration.
