30. Sex cells are always haploid, meaning they have half the number of chromosomes.
Answer:
<u><em>The correct option is ' Organelle A is mitochondrion, Organelle B is chloroplast, and Organelle C is vacuole.'</em></u>
Explanation:
Mitochondria are known as the powerhouse of a cell. It is the site where cellular respiration takes place. As a result of cellular respiration, ATP is produced which is the main energy source for cells to carry out their normal processes. Mitochondria is present both in the plant as well as the animal cells.
Chloroplast is the organelle which is responsible for photosynthesis in plants. Photosynthesis is a process by which plants make their own food by using light energy from the sun. Chloroplast is present in plant cell but absent in an animal cell.
The vacuole is present in both the plant and animal cells. In plant cells the vacuole is bigger and present in the centre of the cell and it gives the cell its shape.
Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
<em>C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂</em>
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
- <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place.
</em>
- <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
