CBA #2 Lots-O-Questions REVIEW!

Front

What are proteins?

Back

Proteins are large biomolecules made up of amino acids. They play crucial roles in the body, including building tissues, acting as enzymes, and supporting immune function.

Front

What is a virus?

Back

A virus is a small infectious agent that requires a host cell to replicate. It consists of genetic material (DNA or RNA) surrounded by a protein coat.

Front

What is a mutation?

Back

A mutation is a change in the nucleotide base sequence of a gene, which can lead to changes in the structure and function of proteins.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What type of bond joins the two strands of nitrogenous bases in DNA?

Back

Hydrogen bonds join the two strands of nitrogenous bases in a DNA molecule, allowing the strands to separate during replication.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and they serve as a primary energy source for the body.

Front

What are lipids?

Back

Lipids are a group of hydrophobic organic molecules, including fats and oils, that are important for energy storage and cell membrane structure.

Front

What is the role of a host cell in viral replication?

Back

A host cell provides the necessary machinery and environment for a virus to replicate its genetic material and produce new virus particles.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules pass through the plasma membrane with the help of transport proteins, without the use of energy.

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.
