Answer 6

All the energy needed for a living process

Question 7

Anaerobic respiration and used cells is called

Answer 7

Fermentation

Question 8

During exercise the human body reacts to increase

Answer 8

The demand for energy

Question 9

The heart rate breathing rate and breath volume increase during exercise. Why?

Answer 9

To supply the muscles with more oxygenated blood

Question 10

Blood flowing through the muscles transports lactic acid to?

Answer 10

The liver

Question 11

When lactic acid is transported to the liver where is it converted back into

Answer 11

Glucose

Question 12

What is oxygen debt

Answer 12

It is the amount of extra oxygen in the body after exercise to react with the accumulated lactic acid and remove it from the cells

Question 13

Define metabolism

Answer 13

Metabolism is the sum of all the reactions in a cell or body

Question 14

The energy is transferred by respiration in cells used by what

Answer 14

The organism

Question 15

The transfer of energy by respiration in cells is used by organisms for what

Answer 15

For the enzymes to control the process of metabolism and synthesizing new molecules

Question 16

How can oxygen production be used to show the rate of photosynthesis

Answer 16

Measure the volume of oxygen produced in a given time

Or

When more oxygen is produced in a given time the rate of photosynthesis is faster
