1

Why is energy important?

Plants and animal cells need energy for biological processes.

2

Name 3 things energy is needed for in plants.

Photosynthesis.
Active transport.
Protein synthesis.

3

Name 3 things energy is needed for in animals.

Muscle contraction.
DNA replication.
Cell division.

4

What would happen if the biological processes stopped?

The plant or animal would die.

5

What happens in the process of photosynthesis?

Energy from light is used to make glucose from water and carbon dioxide.
The light energy converted into chemical energy in form of glucose.

6

What is the overall equation for photosynthesis?

6CO2 + 6H2O + Energy ----> C6H12O6 + 6O2

7

In the plants where is the energy stored?

In the glucose until plants release it by respiration.

8

How to animals obtain glucose?

Eating plants or by eating animals which have eaten plants, then respire releasing energy.

9

Photosynthesis is an example of what?

Metabolic pathway - small reactions controlled by enzymes.
