Metabolic Pathways Matching Guide
This section matches metabolic pathways from Group I with their cellular locations in Group II.
Pathway to Location Mapping
| Group I: Pathway | Group II: Location | Reasoning |
|---|---|---|
| P. Glycolytic pathway | 4. Cytosol | Glycolysis, the initial breakdown of glucose, occurs in the cytosol. |
| Q. Eukaryotic oxidative metabolism | 3. Mitochondria | Major processes of eukaryotic oxidative metabolism, such as the Krebs cycle and electron transport chain, occur in the mitochondria. |
| R. Glyoxylate cycle | 2. Glyoxysomes | The glyoxylate cycle, crucial for converting fats to carbohydrates, is primarily found in glyoxysomes (in plants and microorganisms). |
| S. Calvin cycle | 1. Chloroplast | The Calvin cycle, the light-independent phase of photosynthesis, takes place within the chloroplast. |
Based on these explanations, the correct mapping is P-4, Q-3, R-2, S-1.
Important Questions from Photosynthesis Respiration and Electron Transport Chain

Inhibitor Function P. FCCP 1. Inhibits cytochrome c oxidase Q. Cyanide 2. Makes the membrane permeable to protons R. Oligomycin A 3. Blocks mitochondrial uptake of succinate S. Butyl malonate 4. Inhibits ATP synthase Which of the following are true with regard to anaerobic respiration in bacteria?
P. The final electron acceptor is an inorganic substance other than molecular oxygen
Q. The number of ATP molecules produced per glucose molecule is more than that produced in aerobic respiration
R. The number of ATP molecules produced per glucose molecule is less than that produced in aerobic respiration
S. Only substrate level phosphorylation is used to generate ATP
- ATP biosynthesis takes place utilizing the $H^+$ gradient in mitochondria and chloroplasts. Identify the correct sites of $H^+$ gradient formation.
Match the compounds in Group I with the correct entries in Group II.
Group I Group II P) Cyanide 1) K$^+$ ionophore Q) Antimycin A 2) Electron transfer from cytochrome b to cytochrome c$_1$ R) Valinomycin 3) F$_1$ subunit of ATP synthase S) Aurovertin 4) Cytochrome oxidase 5) Adenine nucleotide translocase - During photorespiration under low $CO_2$ and high $O_2$ levels, $O_2$ reacts with ribulose 1,5- bisphosphate to yield
