Effects of temperature
Increasing temperature increases diffusion up to a certain point, beyond optimum temperature further increases will denature the enzymes.
Effects of pH
If there is a too high or low pH it starts to interfere with the bonds that hold the enzyme in shape. Making it not able to interact with the enzymes.
Carbohydrate digestion
Amylase breaks down carbohydrates in mouth and small intestine into sugars
Protein digestion
Protease breaks down proteins in the stomach pancreas and small intestine into amino acids.
Fat digestion
Fats are broken down by lipase in the small intestine into fatty acids and glycerol
