Enzymes

-Assist metabolic reactions to enhance the speed of reactions; lowers activation energy

-Enzymes are made of amino acids

-Catalyst- they are important to speed up chemical reactions in the body

-Enzymes: Amylase carbohydrates, Pepsin for proteins, Lipase for fats

-Substrate- is the molecule the enzyme acts upon/reacts with

-Active site- region on the enzyme where the substrate binds for the chemical reaction to happen

-The chemical interactions/reactions can bind or may break substrates, position them correctly, and lower activation energy

-How do enzyme attaches: Lock and Key hypothesis

-The lock and key hypothesis proposes that an enzyme's active site has a rigid, pre-determined shape that matches its specific substrate precisely, much like a key fits into a specific lock. When an ezyme attaches to a substrate, the enzymes can bind or break substances to make the reaction happen easier and faster. The lock and key happens in a specific speed, temperature, and ph

-Induced-fit bonding basically refers to when the enzyme and the substrate changes shape and try to adjust in order for them to fit perfectly together

-When an enzyme is denatured the shape changes, becomes a weaker catalyst/ loses its function
