Unit 1 Subtopic 3 - Internal Membrane + Enzymes Flashcards
Define a Cristae in the mitochondria.
It is a fold in the inner membrane in the mitochondrion. It has the characteristic of a wrinkled shape. The purpose is to increase the surface area of the mitochondrial membrane.
Define the Mitochondrial Matrix.
It is a gel-like material that performs cellular respiration. It contains proteins. It converts pyruvate and fatty acids to produce ATP.
What are enzymes and what do they do?
Enzymes are proteins that speed up reaction rates. They themselves are not a part of the experiment however they speed up the reaction by supplying oxygen.
Inhibitors.
Inhibitors, block the active site therefore, stopping the substrate from combining slowing the reaction time.
What is denature??
it causes an enzyme to lose its shape and affects it’s function due to other effecting factors (pH, temperature)
On the pH scale, what is the optimal pH for an enzyme and optimal acidity or base does it function best in?
It is optimal around 6-8 pH, and some work best in acidic conditions.
what happens to an enzyme if the temperature is too extreme?
The enzyme will change it’s shape.
