The correct Answer is:
To solve the question "Which of the following is not the type of facilitated diffusion?", we can follow these steps: ### Step 1: Understand Facilitated Diffusion Facilitated diffusion is a process that allows substances to cross membranes with the assistance of special proteins. It occurs down the concentration gradient (from high to low concentration) and does not require energy (ATP). **Hint:** Remember that facilitated diffusion involves carrier proteins and does not require energy. ### Step 2: Identify Types of Facilitated Diffusion There are three main types of facilitated diffusion: 1. **Symport**: Both substances move in the same direction across the membrane. 2. **Antiport**: Substances move in opposite directions across the membrane. 3. **Uniport**: A single substance is transported across the membrane. **Hint:** Think about how substances move in relation to each other in symport, antiport, and uniport. ### Step 3: Analyze the Options The question provides several options, and we need to identify which one is not a type of facilitated diffusion. The options typically include terms related to transport mechanisms. **Hint:** Look for terms that do not correspond to the types of facilitated diffusion mentioned. ### Step 4: Identify the Incorrect Option From the analysis, "apoport" is mentioned in the video transcript as not being a recognized mechanism associated with facilitated diffusion. Therefore, it is the correct answer to the question. **Hint:** If you see a term that doesn't match the known types of facilitated diffusion, it's likely the answer. ### Step 5: Conclusion The correct answer to the question is the option that includes "apoport," as it is not a type of facilitated diffusion. **Final Answer:** The option that is not a type of facilitated diffusion is "apoport."
