Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules that include sugars and starches, serving as a primary energy source for living organisms.

Front

What is a translocation mutation?

Back

A translocation mutation occurs when a part of one chromosome is transported and attached to a non-homologous chromosome.

Front

How are photosynthesis and cellular respiration similar?

Back

Both processes transfer energy from one form to another.

Front

What is the significance of cellular respiration?

Back

Cellular respiration transforms sugar into a usable form of energy (ATP).

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the active site of an enzyme?

Back

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

Front

What are the products of a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the role of lipids in biological systems?

Back

Lipids serve as long-term energy storage, structural components of cell membranes, and signaling molecules.

Front

What is the difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy (sugar), while cellular respiration converts chemical energy (sugar) into usable energy (ATP).
