B4 Bioenergetics

Question 1

Plants use glucose for 5 ways

Answer 1

For respiration ( transfers energy from glucose ) .
For making animo acids ( glucose is combined with nitrate ions to make amino acids.Amino acids are used to make proteins.
Stored as starch

Question 2

Carbon dioxide + water

Answer 2

Glucose + oxygen

Question 3

At first , the more light there is the

Answer 3

Faster photosynthesis happens

Question 4

The more carbon dioxide there is the

Answer 4

Faster the photosynthesis happens

Question 5

What is respiration

Answer 5

Respiration is the process of transferring energy from the breakdown of glucose

Question 6

Respiration is what type of reaction

Answer 6

Exothermic

Question 7

Three examples of how organisms use the energy transferred by respiration

Answer 7

To build up larger molecules from smaller ones
In animals, to move around
In mamals and birds to keep warm

Question 8

What is metabolism

Answer 8

The sum of all the reactions that take place in a cell or the body

Question 9

Aerobic respiration

Answer 9

Respiration using oxygen

Question 10

Most of the resctions in aerobic respiration happen inside

Answer 10

Mitochondria

Question 11

Word eauation for resporation

Answer 11

Glucose + oxygen - carbon dioxide + water

Question 12

When you do hard excercise your body sometimes can’t supply enough oxygen to your muscles.When this happens

Answer 12

They start doing anaerobic respiration

Question 13

Anaerobic respiration does not transfer anywhere near as much

Answer 13

Energy as aerobic respiration

Question 14

Anaerobic respiration is the incomplete

Answer 14

Breakdown of glucose

Question 15

Anaerobic respiration in yeast cells is called

Answer 15

Fermentation

Question 16

Word eauation for anaerobic respiration in plant and yeast cells

Answer 16

Glucose - ethanol + carbon dioxide

Question 17

Why does anaerobic respirstion not transfer as much energy as aerobic respiration

Answer 17

Because the glucose has not combined with oxygen like it does in aerobic respiration.Oxidation of glucose is not complete

Question 18

When you ecercise somwmof your muscle contract more often so

Answer 18

You need more energy

Question 19

The energy comes from increased

Answer 19

Respiration

Question 20

Increase in respiration in your cells

Answer 20

Breathing rate increases
Your breath volume increases
Heart rate increases

Question 21

When you excercise really hard your bosy can’t supply oxygen to your muscle quickly enough.This means your muscles start doing

Answer 21

Anaerobic respiration

Question 22

Anaerobic respiration is not the best way to transfer energy from glucose because

Answer 22

Lactic acid builds up in the muscles which gets painful
