What is the difference between saturated fats and unsaturated fats?

• Saturated fats are much healthier than unsaturated fats because they are easier to break down.

• Unsaturated fats have a straight structure, while saturated fats have a bent structure.

• Saturated fats have no double bonds between carbon atoms, while unsaturated fats have double bond(s) between carbon atoms.

• Unsaturated fats are usually found solid at room temperature, while saturated fats are usually found as liquid at room temperature.

What does the Lock & Key Model represent?

• The way enzymes and substrates "fit together", where enzymes are specific for each reaction

• When a substrate breaks off from an enzyme, forming a new product

• When a substrate does not fit together with the active site of an enzyme

• When the specific reaction is sped up by the enzyme.

What is the active site of an enzyme?

• the biological molecule that the enzyme works on

• the new biological molecule that is formed once the reaction takes place

• the catalyst that speeds up or causes the reaction between organic molecules

• the specially-shaped area of an enzyme that fits around the molecule being bound to it

Carbohydrates make up _____% of our food intake.

• 75

• 100

• 20

• 60
