biological molecules pt 2

Question 1

what are enzymes?

Answer 1

enzymes are special proteins that act as catalyst in your body, which means they speed up chemical reactions without being used up themselves

Question 2

what temperature do enzymes work best at in the human body?

Answer 2

optimum enzyme activity is at 37 degrees.

Question 3

what is the structure of and enzyme molecule?

Answer 3

enzymes are proteins made up of long chains of amino acids
these long chains fold to produce a 3d shape.

Question 4

what is the enzymes process?

Answer 4

1)substrate enter active site
2)an enzyme-substrate complex forms
3)reaction occurs
4)products form and leave active site

Question 5

what will happen when enzymes are at low temperatures and high temperatures?

Answer 5

there will be insufficient activation at low temp
the enzyme is denatured: its 3d shape has changed at high temperatures

Question 6

what is the optimum pH level for enzymes?

Answer 6

optimum pH level for enzymes is at pH level 7

Question 7

what is an active site?

Answer 7

a specific area of enzyme that is shaped to allow other molecules to fit into it to undergo reaction. Most vital part of enzyme function

Question 8

what is a substrate?

Answer 8

the molecule that fits into the active site to undergo reaction.

Question 9

what is the enzyme-substrate complex?

Answer 9

the structure formed when the substrate and enzyme bind together for the reaction.

Question 10

what is the product?

Answer 10

what is formed after the reaction
