10 flashcards · Other · by Haroon Chehabzada

1. What is ATP and how is it used?

   • ATP is a key molecule in cells • The ATP cycle in cells involves biosynthesis, active transport, oxidation fuel, work molecules, and genetic information transfer

2. What pathways use NAD+/NADH and NADP+/NADPH

   NAD+/NADH pair is used in catabolic enzymes, while the NADP+/NADPH pair is used in anabolic pathways

3. Why is NADH important in metabolism ?

   NADH is a major intermediate acceptor of electrons in metabolism and is involved in the conversion of glucose to ATP

4. Where is FADH and FMN involved?

   In the citric acid cycle and oxidative phosphorylation

5. What does Glycolysis break down?

   Glycolysis breaks down glucose into pyruvate in the cytosol

6. Where does the citric acid cycle take place and what does it produce?

   In the mitochondrial matrix and produces CO2, NADH, FADH2, and ATP

7. What takes place in the inner mitochondrial membrane and produces ATP?

   Oxidative phosphorylation

8. How is metabolic energy derived ?

   Oxidative Reactions

9. How can you generate higher biological energy

   More highly reduced substrates have a higher potential for generating biological energy

10. 3 types of metabolic pathways

    Linear, Circular, Spiral
