Multiple Choice

Explain the process of polymerization and its significance in the formation of biomolecules.

Multiple Choice

Describe the structure and main components of the cell membrane as shown in the diagram.

• The cell membrane is a rigid structure made of cellulose and proteins.
• The cell membrane consists of a phospholipid bilayer, embedded proteins, and cholesterol, forming a semi-permeable barrier that regulates the movement of substances in and out of the cell.
• The cell membrane functions as a solid barrier that does not allow any substances to pass through.
• The cell membrane is composed solely of carbohydrates and nucleic acids.

Open Ended

Name the 2 different endoplasmic reticulum.

Multiple Choice

Ribosomes are originally made where?

• Nucleolus
• Golgi Apparatus
• Endoplasmic Reticulum
• Cytoplasm

Multiple Choice

What cellular structure builds proteins?

• Ribosomes
• Nucleus
• Mitochondria

Multiple Choice

How does the endoplasmic reticulum help with finalizing the making of a protein?

• The endoplasmic reticulum helps finalize protein making by synthesizing, folding, and modifying proteins before they are sent to the Golgi apparatus.
• The endoplasmic reticulum only transports proteins to the nucleus.

Multiple Select

Which of the following statements about osmosis, as shown in the diagram, are correct? (Multi choices)

• Water moves from lower to higher solute concentration through aquaporins.

• Sugar cannot pass through the membrane due to lack of channel proteins.

• Osmosis is a type of passive transport.

• Cell membranes allow all molecules to pass freely.

Open Ended

Compare and contrast the difference between simple diffusion and facilitated diffusion.

Open Ended

Why is osmosis still considered a type of facilitated transport?

Multiple Choice

Why will cells try to move water "first" before any other molecule for homeostasis?

• Cells will try to move water first for homeostasis because it is crucial for maintaining osmotic balance and cellular function.
• Proteins are more important for cellular structure than water.
• Cells prioritize moving glucose for energy needs.
• Oxygen is the first molecule needed for cellular respiration.

Multiple Choice

Multiple Choice

Why does the left ventricle of the heart require so much mitochondria per cell?

• The left ventricle requires many mitochondria to produce the energy needed for its strong contractions to pump blood throughout the body.
• The left ventricle has fewer mitochondria because it relies on anaerobic respiration.
