Question
Which of the following processes occurs in the plasma membrane of a prokaryotic cell?ANSWERElectron transport chainGlycolysis, Krebs cycle, and electron transport chainGlycolysisKrebs cycle
Solution
The process that occurs in the plasma membrane of a prokaryotic cell is the Electron transport chain.
Here's a step-by-step explanation:
-
The plasma membrane of a prokaryotic cell is the site of many processes, including the electron transport chain. This is a series of protein complexes and electron carrier molecules within the plasma membrane that pass electrons from one to another, and in the process, create a proton gradient across the membrane.
-
Glycolysis and the Krebs cycle, on the other hand, are processes that occur in the cytoplasm of the cell, not the plasma membrane.
-
Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy and reducing power in the form of ATP and NADH, respectively.
-
The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into ATP and carbon dioxide.
-
Therefore, among the options provided, the electron transport chain is the process that occurs in the plasma membrane of a prokaryotic cell.
