Respiration

Question 1

What is respiration?

Answer 1

Process of breathing in oxygen and breathing out carbon dioxide

Question 2

Purpose of respiration

Answer 2

To make energy

Question 3

What type of respiration occurs in cytoplasm?

Answer 3

Anaerobic

Question 4

Equation for aerobic respiration

Answer 4

Glucose + oxygen -> carbon dioxide + water + ATP ( energy)

Question 5

What type of respiration releases the most energy per molecule of glucose?

Answer 5

Aerobic

Question 6

3 ways to investigate aerobic respiration in peas/beans?

Answer 6

1) temperature
2) concentration of oxygen
3)concentration of carbon dioxide

Question 7

What’s oxygen debt?

Answer 7

Extra volume of oxygen needed to breathe in when resting after anaerobic exercise.

Question 8

Equation for anaerobic respiration

Answer 8

Glucose -> lactic acid + ATP (energy)

Question 9

Relationship between heart rate and breathing rate

Answer 9

Increase and decrease together
As heart rate increases, breathing rate increases

Question 10

Explain why the breathing rate remains high at the end of a race

Answer 10

In oxygen debt , trying to repay by getting more oxygen.
Anaerobic respiration creates lactic acid

Question 11

Why is anaerobic less efficient than aerobic respiration?

Answer 11

Less ATP produced (2 ATP)
