Which small molecules make up carbohydrates
Glucose / Sugars
Which small molecules make up proteins
Amino acids
Which small molecules (2) make up fats?
Fatty acids and glycerol
What is the substrate for carbohydrase?
Carbohydrates
What is the substrate for protease?
Proteins
What is the substrate for lipase?
Lipids
Which part of an enzyme does the substrate fit into?
Active site
Name three factors that affect enzyme activity
Temperature, pH, Concentration (of enzyme or substrate)
What affect can high temperature have on an enzyme
Denature it
What happens when an enzyme is denatured?
The active site changes shape / Substrate no longer fits
What is formed when a substrate fits into the active site of an enzyme
Enzyme substrate complex
Why is enzyme activity low at low temperature
Less kinetic energy and collisions between enzyme and substrate
What chemical is used to test for starch
Iodine
What colour does iodine turn in the presence of starch
Blue Black
What does optimum conditions mean
The best conditions for enzyme action
Why does an enzyme only catalyse one type of reaction
Active site is only complimentary to one substrate
