substrate-level phosphorylation
in the citric acid (Krebs) cycle, ATP molecules are produced by...?
Reactant; Product
A ______ is a substance that participates in a reaction, while a ______is a substance that is formed by the reaction.
Passive Transport
A process that includes Osmosis, Facilitated diffusion, and diffusion of a solute across a membrane.
Exergonic, DG<0
Couldn't find picture, nor could i explain what it is asking
Heat the solution
How can one speed up the diffusion of a solute in water?
By chancing the shape of the enzymes active site
How does a noncompetitive inhibitor decrease the rate of an enzyme reaction
Pinocytosis engulfs fluids; phagocytosis engulfs solids
How does pinocytosis differ from phagocytosis?
substrate-level phosphorylation
In glycolysis, ATP molecules are produced by?
certain proteins are unique to each membrane
In what ways do the membranes of a eukaryotic cell vary?
Structural Isomers
Know the difference between the structurally.. Look in the slides.
FOR 46-50 USE THIS IMAGE!!!!!!!!
Know water, Oxygen (O2), NADPH, Carbohydrate (ATP SUGAR) and CO2!!!!!
Acetyl CoA
NOT a product of the citric acid (Krebs) cycle
Inhibit the enzyme and thus slow the rates of glycolysis and the citric acid cycle.
Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1, 6-bisphosphate, an early step of glycolysis. In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to...?
