Carbohydrates, Lipids, Proteins, Nucleic Acids.

Front

What is the primary function of proteins in living organisms?

Back

Proteins serve as building blocks for tissues, enzymes, and play a role in biochemical reactions.

Front

What property of lipids allows them to form biological membranes?

Back

Lipids are insoluble in water, which helps regulate the entry and exit of substances in cells.

Front

What is passive transport?

Back

Movement of particles from high to low concentration without the use of energy.

Front

What is the role of nucleic acids in cells?

Back

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

Front

What happens to native species when a nonnative species is introduced into an ecosystem?

Back

Native species may have to compete for resources, leading to an unbalanced ecosystem.

Front

What is the structure of a protein?

Back

Proteins are made up of amino acids linked by peptide bonds, forming polypeptide chains.

Front

Define carbohydrates and their primary function.

Back

Carbohydrates are organic molecules made of carbon, hydrogen, and oxygen, primarily serving as energy sources.

Front

What is the significance of the Punnett square in genetics?

Back

The Punnett square is a tool used to predict the genotypes of offspring from parental genotypes.

Front

What is active transport?

Back

Movement of particles from low to high concentration, requiring energy.
