9 Questions
What is the main difference between catabolism and anabolism?
Catabolism involves breaking down complex molecules, while anabolism involves building complex molecules.
Which statement accurately describes catabolism?
Catabolism involves the degradation of energy-rich fuel molecules to capture chemical energy in the form of ATP.
What is the role of the tricarboxylic acid (TCA) cycle in metabolism?
To oxidize acetyl CoA and produce large amounts of ATP through oxidative phosphorylation.
Which molecule serves as an electron donor in anabolic reactions?
NADPH
What is the primary function of catabolism in metabolism?
To capture chemical energy by breaking down complex molecules.
How does anabolism differ from catabolism in terms of energy?
Anabolism requires energy, while catabolism releases energy.
Which of the following best describes the relationship between ATP and ADP in metabolism?
ATP is converted to ADP and Pi in catabolism to release energy.
In metabolism, what is the purpose of the conversion of building blocks into acetyl CoA?
Acetyl CoA acts as a precursor for subsequent reactions that lead to ATP production.
'Divergent' and 'convergent' processes in metabolism refer to:
'Divergent' refers to catabolism breaking down a wide variety of complex molecules into common end products, while 'convergent' refers to anabolism synthesizing a wide variety of complex molecules from common precursors.
