- What do co-enzymes serve as?
- serve as an electron acceptors (energy shuttle) between different enzymes
- What is the most important co-enzyme?
- (NAD) Nicotinamide Adenine Dincleotide
- What are the energy pathways found in the cytoplasm of prokaryotes?
- glycolysis, fermentation, and citric acid cycle
- What is the make up of NAD?
- its is a composite molecule consisting of 2 linked nucleotides
- Where is the pyrvated oxidation and respiratory chain found in a prokaryote cell
- in the inner face of plasma membrane
- When does the first enzyme in the sequence inhibited?
- When there is a sufficient amout of "end product" accumulated
- What does glucose + ATP form?
- glucose-6-phosphate
- What does isomerization yield?
- fuctose-6-phosphate
- What are cofactors?
- metal ions (Cu, Fe, Mo Mg, etc.)
- What enzyme controls the formation of fuctose-6P to fructose1,6-bisphosphate?
