Question 1

What chemical cell reactions are going on 24/7?

Answer 1

Respiration
Photosynthesis
Protein synthesis

Question 2

Every enzyme has a what?

Answer 2

Active site

Question 3

What is an active site?

Answer 3

The part where it joins onto its substrate to catalyse the reaction

Question 4

Enzymes have a high …

Answer 4

Specificity - usually only work with one substrate

Question 5

How does it work for the enzyme to work?

Answer 5

The substrate has to fit into the active site. If the substrates shape doesn’t fit / match the active sites shape, then the reaction WONT be catalysed

Question 6

What is the enzyme and substrate reaction called?

Answer 6

Lock and key mechanism
