Each enzyme has a specific shaped active site. The substrate has to compliment the active site for the reaction to work.

what happens when lipase breaks down lipids?
They are digested and absorbed in the small intestine

explain and describe the effect of temperature on the reactivity of enzymes
As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. at cooler temperatures the rate of enzyme activity decreases.

why do eggs have a large store of cytoplasm?
Because it contains the nutrients and mitochondria needed for mitosis (cell division) after fertilisation.

how do you calculate the rate of a reaction?
Reactions happen when particles collide with enough energy. It can be calculated from the gradient of a graph(amount of product divided by time of reaction)
