Respiration and Metabolism

Question 1

What is respiration

Answer 1

Process of transferring from glucose which goes on in every cell continuously

Question 2

What kind of reaction is respiration

Answer 2

Exothermic

It transfers energy to the environment

Question 3

How do organisms use the energy transferred

Answer 3

Chemical reactions to build up larger molecules
Movement
Keeping warm

Question 4

What is metabolism

Answer 4

The sum of all the reactions in a cell or body

Question 5

3 examples of reactions that make larger molecules from smaller ones

Answer 5

1. Glucose molecules joined together to form starch, glycogen, cellulose
2. One molecule of glycerol and three fatty acids - lipids
3. Glucose and nitrate ions to make amino acids which are then used to synthesis proteins (make)

Question 6

2 examples of reactions that are larger molecules broken down into smaller ones

Answer 6

1. Glucose broken down in respiration to transfer energy to power all the reaction in the body that make molecules
2. Excess protein broken down to to produce urea to be excreted

Question 7

What is the energy transferred by respiration in cells used by the organism

Answer 7

Continual enzyme controlled processes of metabolism that synthesise new molecules
