Biology Test 2-Enzymes [2.10-2.34]

Preparations for Biology test

What do catalysts do?

speed up chemical reactions by lowering activation energy.

How do enzymes connect?

connect by ribosomes

Anabolic?

build up

Catabolic

break apart

The role of enzymes:

coordinating life process efficiency

How do enzymes work?

by colliding with substrate to form an enzyme-substrate complex

Temperature increases, what happens to kinetic energy?

increases/ works faster at 37 degrees

Temperature to high what happens to kinetic energy?

bonds break and reaction decrease

pH is either?

acidic or alkaline

enzymes have different optimum pH if its to far from optimum it ?

denatures

if pH enzyme environment changes?

it will be not optimal and will decrease

if changes interfere with bonding of active site what would happen?

the shape may change and bonds break in between amino acid chains
