Front

What is an Amino Acid?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. They contain an amino group, a carboxyl group, and a unique side chain (R group) that determines the properties of each amino acid.

Front

What is the function of the Golgi Apparatus?

Back

The Golgi apparatus is an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is Active Transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP) to do so.

Front

What is the Cell Membrane?

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment. It regulates the movement of substances in and out of the cell.

Front

Which organelle has no role in protein synthesis?

Back

The Chloroplasts have no role in protein synthesis; they are primarily involved in photosynthesis.

Front

What is a Nucleic Acid?

Back

Nucleic acids are biopolymers essential for all known forms of life. They include DNA and RNA, which store and transmit genetic information.

Front

What is the role of Ribosomes?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of the Endoplasmic Reticulum?

Back

The endoplasmic reticulum (ER) is an organelle that plays a key role in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the detoxification of certain chemicals.

Front

What is Diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration.
