Formula for diarsenic pentoxide
As2O5
Answer:
The answer is (a). The chemical potential energy stored in organic molecules is converted to chemical energy that can be used to do the work of the cell.
Explanation:
Cellular respiration is the process by which organisms combine oxygen with foodstuff molecules while diverting the chemical energy in these substances into life-sustaining activities and removing carbon dioxide and water as waste products. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bond, especially in molecular oxygen, are replaced by stronger bonds in the products.
Answer:
Impacts on Ocean Life
Coral Reefs.
Oysters, Mussels, Urchins and Starfish.
Zooplankton.
Plants and Algae.
Fish.
Explanation:
The rate of reaction that can be measured in the dark by determining the amount of oxygen gas consumed in a period of time is the rate of respiration.
Why?
Plants can undergo two types of reactions involving oxygen:
- <u>Photosynthesis: </u>In this type of reaction, plants use energy from light to synthesize glucose. The chemical reaction for photosynthesis is: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂, and this reaction produces oxygen gas in the presence of light, that means that to measure the rate of photsynthesis, you'll need to measure the amount of oxgen gas <u>produced</u> in a period of time.
- <u>Respiration:</u> In this type of reaction, plants convert the energy stored in the chemical bonds of molecules such as glucose to obtain energy. The chemical reaction for respiration is: C₆H₁₂O + 6O₂ → 6H₂O + 6CO₂, since this reaction consumes oxygen gas in the dark, that means that to measure the rate of respiration, you'll need to measure the amount of oxygen gas <u>consumed</u> in a period of time.
Have a nice day!
