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>
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
The answer is (c). microspore.
Answer:
The answer to your question is: The first option is correct.
Explanation:
a) The primary function of photosynthesis is to use solar energy to synthesize ATP; the primary function of respiration is to break down ATP to release energy. I think this option describes best the relationship between photosynthesis and cell respiration.
b) The process of photosynthesis only occurs in autotrophs, while cellular respiration only occurs in heterotrophs. Cellular respiration also occurs in plants. So this option is incorrect.
c) Photosynthesis uses solar energy to convert inorganics to energy-rich organics; cellular respiration breaks down organics to synthesize ATP. This option is also posible but is not as complete as the first option.
d) Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time. Photosynthesis occurs in chloroplasts but both photosynthesis and chloroplasts can occurs in plants.
Our global climate and weather on Earth can all be attributed to the ocean. The ocean can absorb large quantities of heat from the Sun, and then distribute it to the land next to it, or transport the heat farther away.
