Wgu Biochemistry Task 4 Essay
1. Describe two important features that make all enzymes catalysts .
A catalyst is a substance which can accelerate the rate of a chemical reaction without going through a chemical change itself. Enzymes are proteins which help accelerate the rate of reactions. Enzymes also lower activation energy without being used. (HudonMiller 2012) After and enzyme and substrate bind it converts the substrate to it’s specific product. The enzyme remains unchanged and it is free to move on to other products as the enzyme itself does not undergo a chemical change during this process. 2. Create an original diagram, or series of diagrams, …show more content…
The proton gradient is formed from the processes that release hydrogen ions from products that contain hydrogen along with the process that transport these ions across the membrane.
NADH and FADH 2 enter the electron transport chain from the CAC. These products donate their electrons to two of the protein complexes in the inner mitochondrial membrane. The ions are moved the the remaining complexes (3,4) with the assistance of coenzyme Q10 and cytochrome C. From here a molecule of oxygen transfers the electrons which forms water. With each transfer of the electrons to complexes 1, 3 and 4 it gives energy in the
