AP/SUPA - Chapter 8: Metabolism, Energy and Enzymes

Front

What is a substrate in the context of enzymes?

Back

A substrate is a molecule upon which an enzyme acts, binding to the enzyme's active site to undergo a chemical reaction.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase', indicating their function as catalysts.

Front

What are enzymes primarily made of?

Back

Enzymes are primarily made of proteins, which are composed of amino acids.

Front

What is the role of the active site in an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is a product in the context of enzyme activity?

Back

A product is the molecule(s) that result from the enzymatic reaction after the substrate has been transformed.

Front

What determines the function of an enzyme?

Back

The shape of the enzyme determines its function, as it affects how the enzyme interacts with its substrate.

Front

What is the importance of enzyme specificity?

Back

Enzyme specificity ensures that enzymes catalyze only specific reactions, preventing unwanted side reactions in biological processes.

Front

How do temperature and pH affect enzyme activity?

Back

Temperature and pH can affect enzyme activity by altering the enzyme's shape, which can enhance or inhibit its ability to bind to substrates.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases or prevents the activity of an enzyme by binding to it.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different site on the enzyme.
