Best Answer

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.

What is the similarities between enzyme and hormone?

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


What does diffusion across the cell membrane cause?

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.


How. do carriers proteins transport substances across cell membranes?

How does a carrier protein work?

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.


Is osmosis a physical or chemical change?

Physical. The water is not changed chemically, it is just moved by diffusion across a membrane.
