Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
through metabolism
Enzymes are catalysts, substances which help to change other substances without being permanetley changed themselves.
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
it contains enzymes which break the starch down to sugar
Yes they do. Enzymes change starch into glucose for cellular respiration.

Action Potential
Both enzymes and receptors have specific sites for the substrates to bind. The receptor causes a response beyond the cell membrane and the enzyme facilitates a chemical change in the substrate. Enzymes can be membrane bound or free floating. Receptors are usually membrane proteins
A change in concentration of solutes on either side of the membrane. Depending on the tonicity of the inner-membrane and the outside of the membrane, plasmolysis or cytolysis may occur.
Carrier Proteins transport molecules from an area of higher concentration on one side of the membrane to an area of lower concentration on the other side.

Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
Carrier proteins facilitates the transport of specific substances through intracellular compartments or across the cell membrane. They bond and then drag the molecules across the bilipid layer, releasing them on the opposite side.
Physical. The water is not changed chemically, it is just moved by diffusion across a membrane.
it contains enzymes which break the starch down to sugar
Transport proteins change shape, much like a folding door
