Question 1
1.
The sum of all the chemical reactions in an organism is called_______
Question 2
2.
All chemical reactions require_______ _______in order for the reaction to begin
Question 3
3.
This energy graph shows a_______ reaction
Question 4
4.
This energy graph shows a_______ reaction

Question 5
5.

Once an ATP molecule is used to release energy (ATP --> ADP + P + ENERGY), that ATP molecule is used up and can never be used again

Question 6
6.

Why would sucrose not get broken down (hydrolysis) into glucose and fructose by the enzyme lactase?

Question 7
7.

Put the steps of this enzyme reaction in order from first to last ....

Question 8
8.

What point on the graph represents the activation energy?

Question 9
9.

Which has more stored energy in this energy graph of an exothermic reaction?

Question 10

Question 12
12.

Drag one of the two reactions to each of the catergories

  • Item 1
  • Item 2
  • Catabolic/Breaking Rx
  • Anabolic/Making Rx
  • 1 substrate broken into 2 products
  • 2 substrates bonded into 1 product
  • Would happen inside the small intestine/digestion
  • Would happen in the mammary glands of female mammals as part of the making milk for their newborns
Question 13
13.

On the graph below, sketch the rate of reaction graph for an enzyme-catalyzed reaction, where the optimal pH is 8

Question 14
14.

on the graph skeleton below, draw a LINE that shows an endothermic reaction WITHOUT an enzyme and then a SECOND LINE that shows the reactions WITH an enzyme. YOU NEED TO DRAW 2 LINES - USE 2 DIFFERENT COLORS OR MAKE ONE SOLID AND ONE DASHED and then LABEL one line "with enzyme" and the other line "without enzyme"

Question 15
15.

Explain HOW enzymes catalyze chemical reactions and then explain WHY enzymes are needed to catalyze chemical reactions in order for an organism to be alive

Question 16
16.

Explain WHAT would happen to the rate of reaction of lipase if it was put into an environment with a pH of 2 (like where pepsin works in the stomach? Then explain WHY that would happen?
