Introduction:
The process of breathing and cellular respiration are closely associated. By breathing, an individual takes oxygen into the lungs and passes it to the blood. The blood carries the oxygen to cells where cellular respiration is carried out. Cellular respiration generates energy that is utilized for various cellular activities. There are several steps in cellular respiration; it includes glycolysis, pyruvate oxidation and citric acid cycle, and oxidative phosphorylation.
Answer to Problem 1CC
Pictorial representation: The Fig. 1 shows the vital concepts in cellular respiration.
Fig.1: Concepts map of cellular respiration.
Explanation of Solution
(a)
Correct answer: Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration which occurs in the cytoplasm of the cell. The glycolysis process results in a breakdown of one glucose molecule into a three-carbon compound called pyruvate.
Hence, the correct answer is glycolysis.
(b)
Correct answer: Pyruvate oxidation and citric acid cycle
Explanation:
Pyruvate oxidation and the citric acid cycle are the second stage of the cellular respiration which takes place in the mitochondria. Here, pyruvate is oxidized into a two-carbon compound called acetyl Co-A. The citric acid cycle then completes the breakdown of glucose to carbon dioxide.
Hence, the correct answer is pyruvate oxidation and citric acid cycle.
(c)
Correct answer: Oxidative phosphorylation
Explanation:
Oxidative phosphorylation is the third stage of the cellular respiration. This involves electron transport and chemiosmosis. Oxidative phosphorylation is responsible for most of the ATP formation during the process of cellular respiration.
Hence, the correct answer is oxidative phosphorylation.
(d)
Correct answer: Oxygen
Explanation: Cellular respiration requires oxygen to trap the electrons in an electron transport chain. This helps in the generation of ATP by oxidative phosphorylation.
Hence, the correct answer is oxygen.
(e)
Correct answer: Electron transport chain
Explanation:
Electron transport chain is a series of an arranged molecular system in the mitochondrial cristae that passes the electrons to generate a proton potential across the inner mitochondrial membrane. This is required for oxidative phosphorylation and chemiosmosis.
Hence, the correct answer is electron transport chain.
(f)
Correct answer: CO2
Explanation:
Cellular respiration oxidizes the glucose and the organic fuels into carbon dioxide (CO2) and water molecules (H2O).
Hence, the correct answer is CO2.
(g)
Correct answer: H2O
Explanation:
Cellular respiration oxidizes the glucose and the organic fuels into carbon dioxide (CO2) and water molecules (H2O).
Hence, the correct answer is H2O.
