Evil Labubu!!!! You lose all your points!!!!
100
This organelle is the site of photosynthesis in plant cells.
What is the chloroplast?
100
This molecule is the main energy carrier used by cells.
What is ATP?
100
Increasing temperature above an enzyme’s optimum can cause this change to the enzyme.
What is denaturation?
100
This environmental factor provides the energy needed for photosynthesis.
What is light?
200
This region of an enzyme is where the substrate binds.
What is the active site?
200
This green pigment absorbs light energy for photosynthesis.
What is chlorophyll?
200
This first stage of cellular respiration occurs in the cytosol.
What is glycolysis?
200
A substance required by some enzymes to function correctly is known by this general term.
What is a cofactor?
200
Increasing this gas can increase the rate of photosynthesis until another factor becomes limiting.
What is carbon dioxide?
300
This model describes how an enzyme changes shape slightly when a substrate binds.
What is the induced-fit model?
300
This stage of photosynthesis occurs in the thylakoid membranes.
What are the light-dependent reactions?
300
This stage of aerobic respiration occurs in the mitochondrial matrix and releases carbon dioxide.
What is the Krebs cycle?
300
As substrate concentration increases, enzyme activity eventually stops increasing because these become fully occupied.
What is the active sites?
300
Plants adapted to hot and dry conditions that initially fix carbon dioxide into a four-carbon compound use this pathway.
What is the C4 pathway?
400
This type of inhibitor competes with the substrate for the enzyme’s active site.
What is a competitive inhibitor?
400
This enzyme fixes carbon dioxide by attaching it to RuBP during the Calvin Cycle.
What is RuBisCO?
400
This molecule acts as the final electron acceptor in the electron transport chain.
What is oxygen?
400
Good Labubu!!!! You can have 1 point!
400
These plants open their stomata mainly at night to reduce water loss.
What are CAM plants?
500
This type of inhibition occurs when a molecule binds away from the active site and changes its shape.
What is a non-competitive inhibition?
500
These three products of the light-dependent reactions are used or produced before the Calvin cycle proceeds.
What are the ATP, NADPH and oxygen?
500
This stage of cellular respiration produces the greatest amount of ATP.
What is the electron transport chain?
500
At low temperatures enzyme-controlled reactions slow because enzyme and substrate molecules experience fewer of these.
What are successful collisions?
500
C4 plants reduce photorespiration by separating initial carbon fixation and the Calvin cycle in these two types of cells.
What are mesophyll cells and bundle sheath cells?
