Metabolism Flashcard

Front

What is the definition of metabolism?

Back

Metabolism is the sum of all chemical reactions in the body.

Front

How does the length of RNA compare to DNA?

Back

RNA is much shorter than DNA.

Front

How are enzymes named?

Back

Enzymes are named after their substrate, with '-ase' as a suffix.

Front

Where is chemical energy stored in cells?

Back

Chemical energy is stored in ATP (adenosine triphosphate).

Front

What role does a rate-limiting enzyme play in a metabolic pathway?

Back

A rate-limiting enzyme catalyzes one step and sets the rate for the entire reaction sequence.

Front

What is the primary function of ATP in metabolism?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical processes.

Front

What are the two main types of metabolism?

Back

The two main types of metabolism are catabolism (breaking down molecules for energy) and anabolism (building up molecules for growth and repair).

Front

What is the role of coenzymes in metabolic reactions?

Back

Coenzymes assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups or electrons.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.

Front

What is the citric acid cycle?

Back

The citric acid cycle (Krebs cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
