Introduction to Metabolism exam Flashcards

All chemical reactions within an organism.

A series of chemical reactions that alter a substrate through multiple steps to produce a final product.

Pathways that release energy by breaking down molecules into smaller ones.

Pathways that require energy to synthesize larger molecules from smaller ones.

Exergonic processes.

Endergonic processes.

The initial molecule that undergoes changes in a metabolic pathway.

Enzymes catalyze each step in the pathway, converting substrates into products.

A process that releases energy.

A process that requires an input of energy.

Large molecules are broken down into smaller components, releasing energy.

Smaller molecules are built up into larger molecules, requiring energy.

The end molecule produced in a metabolic pathway.

Think of a cat breaking down a pyramid into smaller pieces.

Think of building up larger structures from smaller building blocks.

Catabolism breaks down molecules, while anabolism builds up molecules.

Characteristic of catabolic pathways.

Characteristic of anabolic pathways.

They help organisms manage energy and build cellular structures.

A protein that catalyzes chemical reactions in metabolic pathways.

Synthesis of DNA and proteins.

Breaking down glucose during cellular respiration.

Multiple enzymatic steps that convert substrates into final products.

Energy is either released (catabolism) or required (anabolism) in metabolic pathways.

The molecule produced after all enzymatic steps are completed.

Catabolism involves exergonic processes that release energy.

Anabolism involves endergonic processes that require energy.

To transform substrates through a series of enzymatic steps to manage energy and build cellular structures.
