The respiration process in cells takes place in the mitochondria. Let's break down the information and explain each point in detail:
1. Mitochondria are the site of respiration:
- Respiration is the process by which cells convert nutrients into usable energy in the form of ATP (adenosine triphosphate).
- Mitochondria are double-membraned organelles found in most eukaryotic cells and are often referred to as the "powerhouses" of the cell due to their role in ATP production.
- They play a crucial role in cellular respiration, which is the process of breaking down organic molecules to produce energy.
2. First reported by Kingsbury and supported by Hogeboom:
- Kingsbury was an American biologist who first reported the association of respiration with the mitochondria in the early 1920s.
- Hogeboom, another biologist, provided further evidence supporting Kingsbury's findings.
3. Mitochondria are related to the oxidation of:
- Oxidation refers to the process of removing electrons from molecules.
- Mitochondria are involved in the oxidation of various nutrients to generate energy.
- The main nutrients that undergo oxidation in mitochondria are carbohydrates, fats, and proteins.
4. Answer: D (All the above):
- Carbohydrates: Mitochondria oxidize glucose, a type of carbohydrate, through a process called glycolysis and the citric acid cycle to produce ATP.
- Fats: Mitochondria also oxidize fatty acids, which are derived from fats, to generate ATP.
- Proteins: In certain circumstances, when carbohydrates and fats are not available, proteins can be oxidized in the mitochondria to produce energy.
In conclusion, mitochondria are the site of cellular respiration, which involves the oxidation of carbohydrates, fats, and proteins to produce energy. This was first reported by Kingsbury and supported by Hogeboom.
