Enzymes

Question 1

What are catalyst

Answer 1

they are chemical systems that control reactions

Question 2

purpose of enzymes?

Answer 2

changing rate of reactions without being used up in the reaction

Question 3

how do enzymes affect energy levels required for a reaction to begin

Answer 3

they lower the necessary energy levels required and maintain it in a controlled manner at a good temp and good speeds.

Question 4

Example to know

Answer 4

An increase in temperature will increase the speed of
most reactions, however, usually proteins are denatured
at high temperatures, thus they would lose their
functions, which is dangerous for the cell. Enzymes
allow these reactions to proceed at speeds that keep the cell alive.

Question 5

what is the material that the enzyme acts on called and

Answer 5

substrate

Question 6

what does the attachment of the substrate to the enzymes active site creates what?

Answer 6

enzyme-substrate complex

Question 7

factors known to impact enzyme activity

Answer 7

temp
ph level
concentration
