5.6 cellular respiration

Question 1

Suggest why humans are referred to as consumers or heterotrophs.

Answer 1

Humans are referred to as consumers because we rely on other organisms for food

Question 2

Which organisms respire

Answer 2

All living organisms

Question 3

Identify the name of the molecule that ATP is an abbreviation for:

Answer 3

Adenosine triphosphate

Question 4

What is ATP

Answer 4

ATP is a product of cellular respiration and is used to store and transfer energy in cells.

Question 5

Equation for cellular respiration

Answer 5

Glucose+oxygen =carbon dioxide+water+energy(ATP)

Question 6

Describe what happens to chemical energy that is stored in your body.

Answer 6

Chemical energy is stored as glycogen in the liver, or in fatty tissue beneath the skin as fat. Some chemical energy is transformed into other forms such as heat energy.

Question 7

Define the term metabolism.

Answer 7

. It is the conversion of chemical energy, and the growth and repair of cells resulting from thousands of chemical reactions that occur in an organism.

Question 8

Does metabolism occur in plants

Answer 8

Metabolism does occur in plants

Question 9

What is the purpose of aerobic respiration?

Answer 9

The purpose of aerobic respiration is to use the energy reproduced to make ATP so that cells can perform functions.

Question 10

Outline the importance of ATP.

Answer 10

ATP is important because it is used to store and transfer energy in cells.

Question 11

Where does cellular respiration occur

Answer 11

Mitochondria mitochondria

Question 12

Cellular respiration

Answer 12

A process where oxygen and glucose are converted into water and carbon dioxide to make ATP

Question 13

Respiration

Answer 13

Respiration is the decomposition of glucose in our cells

Question 14

aerobic respiration

Answer 14

Decomposition of glucose in our cells with the involvement of oxygen.

Question 15

anaerobic respiration.

Answer 15

The decomposition of glucose without the involvement of oxygen.

Question 16

What molecule that breaks down during respiration

Answer 16

Glucose

Question 17

What type of reaction is respiration

Answer 17

Respiration is a exothermic combustion reaction because it needs oxygen to react.

Question 18

Exothermic reaction

Answer 18

Exothermic reactions are reactions or processes that release energy,

Question 19

What organelle carries out aerobic respiration

Answer 19

Mitochondria

Question 20

When does celluar respiration happen

Answer 20

day and night(always)

Question 21

Waht does carbon dixoide require

Answer 21

a constant supply of glucose

Question 22

What organisms are not preyed upon by other organisms but still used for nutrients whilst still alive

Answer 22

parasites

Question 23

Do plants undergo cellular respiration? Explain your answer.

Answer 23

Yes, plants need a constant supply of energy which they obtain when breaking down glucose during celluar respiration

Question 24

The 10% rule tells us that approximately 10% of energy from one trophic level is passed up to the next trophic level in an ecosystem. Provide reasons for this.

Answer 24

-Energy is used to build molecules that build tissue.

· Energy is used to do the work of cells, such as maintenance and metabolic processes.

· Energy is used in respiration, with much ‘lost’ as heat.
