Transcript text: Which of the following is not a reaction that cells use to get energy from nutrients?
Multiple Choice
glycolysis
fermentation
photosynthesis
cellular respiration
Krebs cycle
Solution
The answer is: photosynthesis.
Explanation for each option:
Glycolysis: This is a metabolic pathway that breaks down glucose to produce energy in the form of ATP. It is a fundamental process used by cells to extract energy from nutrients.
Fermentation: This is an anaerobic process that allows cells to generate energy from nutrients when oxygen is not available. It is used by many organisms to produce ATP.
Photosynthesis: This is a process used by plants, algae, and some bacteria to convert light energy into chemical energy stored in glucose. It is not a process used by cells to get energy from nutrients, but rather to produce nutrients.
Cellular Respiration: This is a process that cells use to convert biochemical energy from nutrients into ATP, and it involves glycolysis, the Krebs cycle, and the electron transport chain.
Krebs Cycle: Also known as the citric acid cycle, this is a key component of cellular respiration, where energy stored in nutrients is released to produce ATP.
Summary:
Photosynthesis is not a reaction that cells use to get energy from nutrients; instead, it is a process to produce nutrients using light energy.
