The process in which energy-poor, inorganic, and oxidized compounds of carbon and hydrogen are reduced to energy-rich carbohydrates (glucose) using light energy that is converted into chemical energy by chlorophyll and other pigments is called:

Correct answer: B. Photosynthesis

  • A. Bioenergetics
  • B. Photosynthesis
  • C. Aerobic respiration
  • D. Anerobic respiration

Explanation

Photosynthesis is the process in which light energy is absorbed by chlorophyll and other pigments to convert inorganic compounds such as carbon dioxide and water into energy-rich carbohydrates like glucose. This process is an essential part of bioenergetics, which studies the conversion and flow of energy in biological systems. In contrast, aerobic respiration is the complete oxidation of glucose in the presence of oxygen, producing carbon dioxide, water, and a large amount of energy. Anaerobic respiration, on the other hand, occurs without oxygen and yields less energy, resulting in byproducts such as lactic acid.

About Bioenergetics

Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
