Respiration

Question 1

What is Respiration?

Answer 1

The process that releases chemical energy in the body. Release of chemical energy from glucose. Cells convert food into ATP.

Question 2

What is ADP?

Answer 2

When the bonds in the ATP molecule breaks they release energy and form ADP and phosphate (pi).

Question 3

3 Uses of ATP

Answer 3

• Active Transport
• Heat
• Nerve Impulses

Question 4

What is Glycolysis?

Answer 4

A 6-Carbon glucose molecule is broken down by enzyme controlled reactions into 3-Carbon molecules of pyruvate. Occurs in cytoplasm.

Question 5

What is Aerobic Respiration?

Answer 5

Glucose + Oxygen > Carbon Dioxide + Water + Energy

Question 6

Stage One of Aerobic Respiration

Answer 6

Glucose is broken down into two molecules of pyruvate. Every glucose molecule that is broken down also makes 2 ATP molecules.

Question 7

Stage Two of Aerobic Respiration

Answer 7

A pyruvate molecule enters the mitochondria and is broken down because of oxygen, this produces carbon dioxide and water. The energy released from each pyruvate molecule produces a large number of ATP.

Question 8

What is Fermentation?

Answer 8

The breakdown of glucose when no oxygen present.

Question 9

What is Fermentation in Animals?

Answer 9

Glucose > Lactic Acid + Small Amount of ATP

Question 10

What is Fermentation in Plants?

Answer 10

Glucose > Carbon Dioxide + Ethanol + Energy
