yesterday - answer the questions below.

1. molecules are transported across the cell membrane. look at each image and identify the type of transport.

write the letter in the correct box. make sure you choose the most specific answer.
a. active transport b. facilitative diffusion c. osmosis d. phagocytosis e. pinocytosis f. simple diffusion

Explanation:

All Year Section (1 - 4)

1.

• Explanation: The diagram shows molecules moving from low to high concentration (against the gradient), which requires energy, so it's Active transport (C).
• Answer: C. Active transport

2.

• Explanation: The structure is a glucose molecule (a 6 - carbon sugar structure), so it's D.
• Answer: D. Glucose

3.

• Explanation: The structure has adenine, ribose, and three phosphate groups, which is ATP (A).
• Answer: A. ATP

4.

• Explanation: Molecules are moving from high to low concentration (down the gradient) without energy, so it's Passive transport (B).
• Answer: B. Passive transport

Yesterday Section (5 - Image - based)

First Image (Glucose transport: 0.3% to 0% glucose)

• Explanation: Glucose moving from higher to lower concentration but through a protein (since glucose is polar), so it's Facilitative Diffusion (B).
• Answer: B. Facilitative Diffusion

Second Image (Liquid uptake)

• Explanation: Cell taking in liquid, which is Pinocytosis (E).
• Answer: E. Pinocytosis

Third Image (Na⁺ transport: 155 to 19 units)

• Explanation: Na⁺ moving from low to high concentration (against gradient), so it's Active Transport (A).
• Answer: A. Active Transport

Fourth Image (O₂ transport: 100 to 40 units)

• Explanation: O₂ is non - polar, moving from high to low concentration directly through membrane, so it's Simple Diffusion (F).
• Answer: F. Simple Diffusion

Fifth Image (Water transport: 100% to 94% water)

• Explanation: Water moving across membrane, so it's Osmosis (C).
• Answer: C. Osmosis

Sixth Image (Large particle uptake)

• Explanation: Cell taking in a large particle, which is Phagocytosis (D).
• Answer: D. Phagocytosis
