Enzyme Structure
What is the location where the reaction occurs called?
Active site.
What does enzyme catabolism do?
Breaks down complex molecules.
What is an allosteric enzyme?
1 active site, 1 allosteric site.
Photosynthesis first evolved in what organisms?
Prokaryotic.
A process in the mitochondria that generates ATP.
What are the reactants called in enzyme reactions?
Substrates
What does enzyme anabolism do?
Builds complex molecules.
When molecules bind to an allosteric site it changes shape and function.
What are chloroplasts surrounded by?
A double membrane.
Is glucose oxidized or reduced?
Oxidized.
What is induced fit?
Enzymes that change shape to allow substrate to fit better.
What happens if the shape of the enzyme is changed?
The reaction changes.
What is it called when the substrate bonds to an allosteric site to stabilize the shape of the enzyme, and where the active site remains open?
Allosteric activator.
How does photosynthesis split H20?
Into h and o
What is produced at the end of Glycolysis?
How are substrates held on active site?
Through weak interactions.
What is a competitive inhibitor?
Blocks substrates from active site.
Substrates bind to the allosteric site but the active site closes.
What are the 2 stages of photosynthesis?
Calvin cycle, and light reactions.
What does pyruvate turn into?
Acetyl COa
What are factors that can affect enzyme shape.
Temperature, PH
What is a noncompetitive inhibitor?
Binds to another spot on the enzyme changing shape, preventing the substrate from bonding.
What is feedback inhibition?
This is when the end product acts as an inhibitor to an early enzyme in the same pathway.
What is the formula for photosynthesis?
6co2+6H20+Light energy=c6h12o6+602
What are the three stages of cellular respiration?
Glycolysis, Pyruvate oxidation and citrid acid cycle, ETC
