Question

1. Name the following:
(1) Cell organelle where Krebs cycle takes place.
(ii) End product of anaerobic respiration.
(iii) Two important phases of aerobic respiration.
(iv) Two end product of glycolysis.
(v) Part of cell where glycolysis takes place.
2. How does exchange of gases takes place in stem and leaves?​

Answer 1

Answer:

Aerobic respiration is the process that leads to a complete oxidation of organic substances in the presence of oxygen, and releases CO

2

, water and a large amount of energy present in the substrate. For aerobic respiration to take place within the mitochondria, the final product of glycolysis, pyruvate is transported from the cytoplasm into the mitochondria. The first process takes place in the matrix of the mitochondria while the second process is located on the inner membrane of the mitochondria.

Hence, the cell organelle in which Kreb's cycle occurs is mitochondria.

Answer 2

Explanation:

1)Krebs cycle takes place in mitochondria

2)if anaerobic respiration is taking place in muscles then the end product will be lactic acid and if we consider fermentation then the product will be ethanol +CO2

3)glycolysis takes place in all that means in aerobic as well as anaerobic pathway . In aerobic respiration acetyl CoA formation then tricarboxyluc acid cycle(Krebs cycle) then electron transport system or Oxidative phosphorylation takes place

4)end product of glycolysis is 2 molecules of pyruvic acid (for more correct answer u can check ncert page no. 229)

5)glycolysis takes place in cytoplasm
