certain enzymatic reactions are constrained in microcompartments because ______.

• the reaction requires a different ph that can be maintained in a microcompartment
• a reactant is a gas that could easily pass through a membrane
• the reaction products are magnetic and could influence the motility of the bacteria
• the reaction produces a toxic intermediate
• the reaction product will be stored until it is needed by the cell

Explanation:

• For "the reaction requires a different pH that can be maintained in a microcompartment": Microcompartments can isolate regions with specific pH, suitable for reactions needing unique pH, so this applies.
• For "a reactant is a gas that could easily pass through a membrane": Microcompartments can concentrate gaseous reactants (even if they pass membranes, the compartment helps localize them), so this applies.
• For "the reaction products are magnetic and could influence the motility of the bacteria": Enzymatic reaction products in cells are rarely magnetic to affect motility, so this does not apply.
• For "the reaction produces a toxic intermediate": Microcompartments can sequester toxic intermediates to prevent harm to the cell, so this applies.
• For "the reaction product will be stored until it is needed by the cell": Microcompartments can store products for later use, so this applies.

Answer:

• the reaction requires a different pH that can be maintained in a microcompartment
• a reactant is a gas that could easily pass through a membrane
• the reaction produces a toxic intermediate
• the reaction product will be stored until it is needed by the cell
