Question

1. the green aquatic plant represented in the diagram below was exposed to light for several hours. which gas would most likely be found in the greatest amount in the bubbles? a. oxygen b. nitrogen c. ozone d. carbon dioxide 21. the production of energy - rich atp molecules is the direct result of a. recycling light energy to be used in the process of photosynthesis b. releasing the stored energy of organic compounds by the process of respiratio c. breaking down starch by the process of digestion d. copying coded information during the process of protein synthesis 22. an investigation was carried out and the results are shown in the diagrams. substances resulted from a metabolic process that produces atp in yeast (a single - celled fungus). which statement best describes substance x? a. it is oxygen released by protein synth b. it is glucose that was produced in ph c. it is starch that was produced durin d. it is carbon dioxide released by res

Explanation:

• For question 20: Green plants perform photosynthesis in the presence of light, which produces oxygen as a by - product. So the gas in the bubbles is most likely oxygen.
• For question 21: ATP is produced by the process of respiration which releases the stored energy of organic compounds.
• For question 22: Yeast undergoes fermentation (a type of respiration in the absence of oxygen) using sugar. One of the products of yeast fermentation is carbon dioxide.

Answer:

1. A. oxygen
2. B. releasing the stored energy of organic compounds by the process of respiration
3. D. It is carbon dioxide released by respiration
