Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+. A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA. The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.
Explanation:
Is called the cell membrane
Answer:
Vitamin C
Explanation:
Vitamin C is known as the ascorbic acid performs various functions in humans and is present as the constituent of the skin epidermis.
Vitamin C protects the skin from photodamage caused by the harmful UV radiations and helps in the synthesis of collagen, a type of connective tissue in the human body.
Vitamin C is involved in the hydroxylation of collagen synthesis which is important for the support of the epidermis and extracellular stability.
The deficiency of Vitamin C causes scurvy characterized y the fragility of blood vessels and bleeding.
Thus, Vitamin C is the correct answer.
When a fish swims from salt water into fresh water its cells react by losing water and shrinking. The correct option is D.
<h3>What is fresh water?</h3>
Glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands, and even groundwater contain fresh water.
These freshwater habitats cover less than 1% of the world's total surface area but are home to 10% of all known animals and up to 40% of all known fish species.
When a fish swims from salt water into fresh water its cells react by losing water and shrinking due to osmosis.
Thus, the correct option is D.
