Enzyme Terminology
Most common names for enzymes end in this suffix
What is -ase?
This organelle is where photosynthesis occurs
What is a chloroplast
This enzyme is responsible for fixing CO₂ to RuBP.
What is Rubisco?
The Calvin Cycle occurs in this fluid-filled region of the chloroplast.
What is Stroma?
Glycolysis begins with a single molecule of this six-sided compound.
What is Glucose?
The area of an enzyme where substrates bind
What is an active site?
These are the disks that increase surface area for the light reactions to occur
What are thylakoids?
This 3-carbon molecule is the direct product of the Calvin Cycle.
What is G3P (glyceraldehyde-3-phosphate)?
The Krebs Cycle occurs in this specific part of the mitochondrion.
What is the Mitochondrial matrix?
Glycolysis occurs in this part of the cell.
What is Cytosol (cytoplasm)?
Enzymes that phosphorylate substrates
What is a kinase?
This excited molecule is the very first electron donor in Photosystem II.
What is Water (H₂O)
The molecule is regenerated at the end of the Calvin Cycle to keep the cycle going.
What is RuBP?
The electron transport chain of cellular respiration is embedded in this membrane.
What is the Inner mitochondrial membrane (Cristae)?
The net ATP gain from glycolysis is this many ATP molecules.
What is 2 ATP?
Metal ions are examples of this protein required for an enzymes functional activity.
What is cofactor?
This enzyme uses the H⁺ gradient to produce ATP in the light reactions.
What is ATP synthase?
For every three molecules of CO₂ entering the cycle, only one of these molecules exits to build glucose.
What is One G3P molecule?
Light-dependent reactions pump H⁺ into this space to create a gradient.
What is the Thylakoid lumen?
This electron carrier is reduced during glycolysis.
What is NAD⁺?
The alternate site on an enzyme where noncompetitive inhibitor could attach.
What is an allosteric site?
During the light-dependent reactions, electrons leaving Photosystem I do not return to the reaction-center chlorophyll. Instead, they are transferred to this molecule, which becomes the final electron acceptor of the light reactions.
What is NADP+?
ATP and NADPH used in the Calvin Cycle come from these reactions
What are the Light-dependent reactions?
Pyruvate oxidation (the link reaction) occurs as pyruvate moves through this mitochondrial boundary.
What is from Mitochondrial intermembrane space/ into the mitochondrial matrix?
Glycolysis produces two molecules of this three-carbon compound.
What is Pyruvate?
