DC Biology Chapter 4,5, and 6 Test Review

Front

What is a monomer for a protein?

Back

Amino acids are the monomers that make up proteins.

Front

How does the surface area to volume ratio change as a cell gets smaller?

Back

As the cell gets smaller, the surface area to volume ratio increases.

Front

What is a hydrolysis reaction?

Back

A hydrolysis reaction is a chemical process that splits a molecule by adding water, such as the breakdown of fats into glycerol and fatty acids.

Front

What is a nucleotide?

Back

A nucleotide is the monomer unit of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is a glycosidic linkage?

Back

A glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which can be another carbohydrate.

Front

What is the function of proteins in biological systems?

Back

Proteins serve various functions including catalyzing biochemical reactions (enzymes), providing structural support, and facilitating communication between cells.

Front

What is the difference between dehydration synthesis and hydrolysis?

Back

Dehydration synthesis involves the removal of water to form a bond, while hydrolysis involves the addition of water to break a bond.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy required.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond formed between two amino acids during protein synthesis.
