Place the following in the correct order as they occur in CELL RESPIRATION.
Goryan [66]
  1. Electrons and h+ ions pop off and are picked up by NADH.
  2. 1 C is stripped from 3-C PGA and makes Co2.
  3. Coenzyme A attaches to 2-C molecule making Acetyl Co-A.
  4. Resulting 3 C molecule is stabilized BEFORE entering the mitochondria.
  5. Acetyl Co-A enters mitochondria and drops off 2-C molecules.
  6. In cytosol, 6-C glucose and 2 ATP split into two 3-C molecules (glycolysis).
  7. 2-C molecule combines with 4-C molecule and breaks into two 3-C molecules
  8. Krebs cycle spins twice; each time stripping 1 carbon to make Co2 as a by-product.
  9. With each cycle of Krebs, electrons and H+ ions pop off, are picked up by NADH and FADH2 and taken to ETC
  10. 4 molecules of ATP are generated.

The image shows a magnified view of a leaf's surface with the stomata visible. What’s the significance of these structures in th
Deffense [45]

The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.

Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.

The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.

Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.

Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
