R/Variable Group, CHON elements
300
What are 2 examples of nucleic acids
DNA, RNA, and ATP
300
Which line shows a reaction where an enzyme is present?
The red line because it has lower activation energy.

What 3 things are essential in the structure of a nucleic acid?
A Sugar, a Nitrogenous Base, and a Phosphate Group
500
What is the optimal temperature for this enzyme? What temperature would you keep it at to slow down enzyme activity without denaturing the enzyme?
Optimal = between 60 degrees
Temperature to slow activity = ~30 degrees
500
Double Jeopardy:
Explain why the graph hits a plateau.
All enzymes are occupied so adding additional substrate (as measured by the X axis) does not increase the rate of react/enzyme activity (as measured by the Y axis). All enzymes being occupied means additional substrates does not yield additional enzyme activity/reactions.

The structure of cellulose is shown below. How does this structure relate to cellulose being in the cell wall?
Cellulose has a rigid, line structure. This provides the rigid structure of the cell wall that provides structure for plant cells.
