Question

The final electron acceptor in cellular respiration IS Glycolysis occurs in the the cell. 0 The enzymes for the citric acid cycle are located in the: Which type of respiration is more efficient at producing ATP? Anaerobic or Aerobic (circle one) s What is the name of the molecule which allows protons to flow across the inner mitochondrial membrane? The electrochemical gradient is established in the . Lactic acid fermentation occurs in our cells. Molecules called electrons to the ETC shuttle Describe a reduction reaction. o Where are the cytochromes of the ETC located?

Explanation / Answer

1. ANS:In cellular respiration, the final electron acceptor in the electron transport chain is oxygen.

(In photosynthesis final electron acceptor is NADP)

2. ANS: Glycolysis occur in the cytoplasm of the cell.

3. ANS: Citric acid cycle enzymes are located in mitochondrial matrix space.

4. ANS: Aerobic

5. ANS: Complex V (The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis)

6. ANS: An electrochemical gradient is a gradient of electrochemical potential, usually for an ion that can move across a membrane. The gradient consists of two parts, the electrical potential and a difference in the chemical concentration across a membrane. The difference of electrochemical potentials can be interpreted as a type of potential energy available for work in a cell. The energy is stored in the form of chemical potential, which accounts for an ion's concentration gradient across a cell membrane, and electrostatic energy, which accounts for an ion's tendency to move under influence of the transmembrane potential.4. ANS:

7. ANS: lactic acid fermentation occurs in our muscle cells.

9. ANS: Reduction is the gain of an electron, and oxidation is the loss of an electron and Oxidation reactions and reduction reactions occur independently.
