Accepted Answer

### Question 15:
#### a.
# Explanation:
## Step1: Analyze glucose concentration
The cell has 3 glucose molecules, and the blood has more (let's count: around 8). So blood has higher concentration.
## Step2: Determine the region
Higher concentration of glucose is in the blood (since cell has fewer glucose molecules than blood).
# Answer: Blood

#### b.
# Explanation:
## Step1: Recall transport types
Glucose uses helper proteins (carrier proteins) in cell membrane, moving from high (blood) to low (cell) or vice versa? Wait, after digestion, glucose moves into cells. Wait, the cell has 3, blood has more? Wait no, maybe I miscounted. Wait the cell has 3 glucose (triangles), blood has more (like 8). Wait, no—maybe after digestion, glucose is absorbed into blood, then into cells. Wait, the diagram: cell has 3, blood has more. So glucose moves from blood (high) to cell (low)? But with helper proteins. So it's facilitated diffusion? Wait, no—if cell needs glucose, maybe cell has lower concentration. Wait, maybe the cell has lower concentration (3) than blood (more), so glucose moves into cell via facilitated diffusion (uses helper proteins, passive transport). So the specific type is facilitated diffusion.
# Answer: Facilitated Diffusion

#### c.
# Explanation:
## Step1: Recall active/passive transport
Facilitated diffusion is passive (moves down concentration gradient, no energy needed).
# Answer: Passive

#### d.
# Explanation:
## Step1: Determine movement direction
Glucose moves from blood (higher concentration) into cell (lower concentration). So draw an arrow from blood (triangles outside cell) into the cell (towards the cell's interior).
# Answer: Arrow from blood (outside cell) to inside the cell (towards the cell with 3 glucose molecules).

### Question 16:
#### a.
# Explanation:
## Step1: Identify transport type for large particles into cell
Movement of large particles into cell is endocytosis (specifically, maybe phagocytosis or pinocytosis, but general term is endocytosis).
# Answer: Endocytosis

#### b.
# Explanation:
## Step1: Analyze concentration direction
Endocytosis moves particles into cell, usually from lower to higher concentration (or regardless, but the diagram shows particles outside, moving into cell. Wait, the concentration: outside has more? Wait the diagram: outside has dots, inside cell has more? No, the arrows are moving into cell. Wait, endocytosis is active transport, moving against or regardless? Wait, the molecules being moved: large particles. The concentration: outside (extracellular) to inside (intracellular). So from extracellular (outside) concentration to intracellular (inside) concentration.
# Answer: Extracellular (Outside) → Intracellular (Inside)

#### c.
# Explanation:
## Step1: Recall energy requirement for endocytosis
Endocytosis is active transport, which requires energy (ATP).
# Answer: Yes

### Question 17:
#### a.
# Explanation:
## Step1: Identify transport type for large particles out of cell
Movement of large particles out of cell is exocytosis.
# Answer: Exocytosis

#### b.
# Explanation:
## Step1: Recall active/passive for exocytosis
Exocytosis is active transport (requires energy, moves substances out, like waste or secretions).
# Answer: Active

#### c.
# Explanation:
## Step1: Determine substances moved by exocytosis
Substances like waste products, hormones, neurotransmitters, or large molecules (e.g., proteins, polysaccharides) are moved out via exocytosis.
# Answer: Large molecules (e.g., proteins, hormones, waste), or secretory products (like enzymes, neurotransmitters)
