What is the difference between animal and plant cells?
They have a nucleus, cytoplasm, cell membrane, and mitochondria. Except plants have a few extra things, cell wall, vacuole, chloroplasts.

What is the function of the nucleus, cytoplasm and mitrochondria?
Nucleus: contains DNA, instructions for making proteins. Cytoplasm: proteins(enzymes are made). Mitrochondria: this is where enzymes are needed for the reactions of aerobic respiration.

Describe the lock and key model?
The substrate fits into the enzyme (in the active site) like a lock and key each substrate fits a specific enzyme.
3 of 12
What is the function of a enzyme?
Enzymes are proteins that speed up chemical reactions.
4 of 12
What is a denaturised enzyme?
All enzymes had an optinum pH (40 degrees) that they work best at. If the pH is to high or low it interferes with bonds holding the enzyme together. This changes the shape of the active site and denatures the enyzme, causing it to stop working.

What is the word equation for photosynthesis?
Carbon dioxide+ water= glucose+ oxygen. It is a series of chemical reactions that uses energy from sunlight to produce food
6 of 12
What is respiration?
It is a series of chemical reactions that release energy by breaking down large food molecules. It happened in every living cell . The word equation is: Glucose+oxygen=carbon dioxide+water
7 of 12
What is the difference between anaerobic and aerobic respiration?
Aerobic is with oxygen, anaerobic is without.
8 of 12
Three factor that can limit the rate of photosynthesis?
Light carbon dioxide and temperature.
9 of 12
What is diffusion?
Itis the movement of particles from a region of high concentration to low conc.
10 of 12
What is active transport?
It is the movement of water molecules.
