Q

What is an enzyme?

A

20
Q

What is the ‘lock and key’ model?

A

Where only one substrate fits into a enzyme.

21
Q

How do enzymes work?

A

Enzymes and substrates collide to form enzyme-substrate complexes
The substrates are broken down.
The products are released.
The enzyme is free to act again.

22

Magnification=image size / actual size

23
Q

What is the equation for actual size?

A

Actual size= image size / magnification

24
Q

What is the equation for image size?

A

Image size = actual size x magnification

25
