Q1: Define respiration. Why is it essential for plants?
Respiration is a catabolic process in which organic compounds are oxidized to release energy in the form of ATP. In plants, it occurs continuously in all living cells.
Essential for:
- Providing ATP (energy currency) for all life processes
- Biosynthetic reactions (protein, nucleic acid synthesis)
-...
Q2: What are the stages of aerobic respiration?
Aerobic respiration has three stages:
1. Glycolysis (cytoplasm): Glucose (6C) → 2 Pyruvate (3C) + 2 ATP + 2 NADH
2. Krebs cycle/Citric Acid Cycle (mitochondrial matrix): Acetyl-CoA completely oxidized, releases CO2 + 8 NADH + 2 FADH2 + 2 ATP
3. Electron Transport Chain (inner mitochondrial membrane)...
Q3: Describe glycolysis. Where does it occur and what are its products?
Glycolysis is the breakdown of one molecule of glucose (6C) into two molecules of pyruvate (3C).
Location: Cytoplasm
Main steps:
- Glucose → Glucose-6-phosphate → Fructose-1,6-bisphosphate (uses 2 ATP)
- Fructose-1,6-bisphosphate → 2 G3P (3-carbon molecules)
- G3P → Pyruvate (produces 4 ATP + 2 NADH...
