Minerals are inorganic substances and are not considered biological molecules.

Carbohydrates serve as the primary source of energy for cells.

Phospholipids are the main components of cell membranes due to their amphipathic nature.

Proteins act as enzymes, catalyzing and facilitating biochemical reactions.

ATP and ADP are nucleotides, not nucleic acids.

DNA stores and transmits genetic information.

mRNA carries the genetic code from DNA to the ribosome for protein synthesis.

Enzymes accelerate the rate of biochemical reactions by lowering the activation energy.

Minerals are not enzyme cofactors.

Coenzymes participate in electron transfer reactions.

Nucleotides are not macromolecules but are building blocks of nucleic acids.

Hormones act as chemical messengers, regulating various physiological processes.

Proteins can act as buffers, but they are not typically referred to as biological buffers.

Biological buffers help maintain a stable pH in biological fluids.

Cell walls are not biological membranes but are found in plant cells.
