What is the role of ATP in cellular processes?

Back

ATP provides the energy required for various cellular activities, including movement, synthesis of molecules, and active transport.

Front

What do both prokaryotes and eukaryotes have in common?

Back

Both prokaryotes and eukaryotes contain genetic material (DNA).

Front

Why is carbon considered a versatile element in organic chemistry?

Back

Carbon can form four covalent bonds, allowing it to create a wide variety of complex molecules.

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates primarily store energy and provide structural support.

Front

What is the main function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What are lipids and their primary functions?

Back

Lipids are a group of hydrophobic molecules that store energy, form cell membranes, and serve as signaling molecules.

Front

What is the significance of covalent bonds in organic molecules?

Back

Covalent bonds allow for the stable connection of atoms in organic molecules, enabling the formation of complex structures.

Front

How do enzymes function in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.
