Multiple Choice
In the process of cellular respiration, what two crucial resources are provided by glucose?
A
Energy and carbon skeletons
B
Oxygen and carbon dioxide
C
NADH and FADH2
D
Water and ATP
Verified step by step guidance
1
Understand that cellular respiration is a metabolic process that converts glucose into energy in the form of ATP, and it also produces other molecules necessary for cellular functions.
Recognize that glucose is a primary source of energy for cells. During cellular respiration, glucose is broken down through glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP.
Identify that glucose also provides carbon skeletons, which are the carbon-based structures used to build other organic molecules within the cell. These are essential for biosynthesis and cellular repair.
Consider the options given: Energy and carbon skeletons are directly derived from glucose, while oxygen and carbon dioxide, NADH and FADH2, and water and ATP are either inputs, intermediates, or outputs of the cellular respiration process.
Conclude that the two crucial resources provided by glucose in cellular respiration are energy (in the form of ATP) and carbon skeletons, which are used for various biosynthetic pathways.
