Respiration

Question 1

Define respiration:

Answer 1

The process of transferring energy from glucose

Question 2

What is the energy from respiration used for:

Answer 2

Respiring, contracting muscles to move, making larger molecules and keeping body temperature stable

Question 3

Define metabolism:

Answer 3

All the chemical reactions occurring in an organism

Question 4

What is aerobic respiration:

Answer 4

Respiration that requires oxygen

Question 5

What are the equations for aerobic respiration:

Answer 5

Glucose + oxygen —> carbon dioxide + water

C(6)H(12)O(6) + 6O(2) —> 6CO(2) + 6H(2)O

Question 6

What is anaerobic respiration:

Answer 6

Respiration that doesn’t require oxygen

Question 7

What is the equation for anaerobic respiration:

Answer 7

Glucose —> lactic acid

Question 8

Which type of respiration is more efficient and provides more energy:

Answer 8

Aerobic

Question 9

What is the equation for anaerobic respiration in plants and yeast:

Answer 9

Glucose —> ethanol + carbon dioxide

Question 10

What is anaerobic respiration called in yeast:

Answer 10

Fermentation

Question 11

When you exercise, you need more energy so you:

Answer 11

Respire more

Question 12

In order to respire more, the body increases:

Answer 12

Heart rate, breathing rate and breath volume

Question 13

What does lactic acid cause:

Answer 13

Pain such as cramp

Question 14

What is an oxygen debt:

Answer 14

The amount of oxygen required to react with all the lactic acid (to produce carbon dioxide and water)

Question 15

What is an alternative way of dealing with lactic acid (not reacting with oxygen):

Answer 15

It is transported to the liver by the blood, where it is converted back to glucose
