Bio II Semester 1 Review

Front

What is the stage of mitosis where chromosomes are unraveling inside the nuclei?

Back

Telophase

Front

What type of bond allows water molecules to form hydrogen bonds with each other?

Back

Polar covalent bond

Front

What is the primary form of information transmission throughout the body?

Back

Chemicals

Front

Where would hydrophobic amino acids typically be found in a protein structure?

Back

Inside the protein (away from water)

Front

What is a kinase?

Back

An enzyme that catalyzes the transfer of phosphate groups from high-energy donor molecules, such as ATP, to specific substrates.

Front

What happens during prophase of mitosis?

Back

The chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the role of metaphase in mitosis?

Back

Chromosomes align at the cell's equatorial plate before being separated.

Front

What is the significance of disulfide bonds in proteins?

Back

They help stabilize the protein's three-dimensional structure.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the function of enzymes in biological systems?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.
