Biology FALL Final Review 2022

Front

What happens during the G1 phase of the cell cycle?

Back

Cell growth occurs during the G1 phase, where the cell increases in size and synthesizes proteins necessary for DNA replication.

Front

What is the effect of an inhibitor on an enzyme?

Back

An inhibitor prevents a substrate from attaching to the enzyme, thereby inhibiting the enzyme's activity.

Front

What happens during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell prepares for mitosis by producing proteins and organelles needed for cell division.

Front

How is energy released from ATP?

Back

Energy is released from ATP when a phosphate group is removed, converting ATP to ADP (adenosine diphosphate).

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What is the function of DNA replication?

Back

DNA replication ensures that each new cell receives an exact copy of the DNA during cell division.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in multicellular organisms, ensuring proper cell division.

Front

What is apoptosis?

Back

Apoptosis is the programmed cell death that occurs in multicellular organisms as a normal part of growth and development.
