Question

Question 13 In ALL exergonic reactions, the products have more total energy than the reactants. the reactions are nonspontaneous. a net input of energy from the surroundings is required for the reactions to proceed. the reaction proceeds with a net release of free energy. some reactants will be converted to products. Question 14 bind two or more ions or molecules and transport them in opposite directions acr Symporters Uniporters Dual transporters Channel pumps Antiporters M

Answer 1

Question 13

Option D: Exergonic reactions proceed with a net release of free energy.

Exergonic reactions can be defined as the reactions that have a negative ∆G and release free energy during the reaction. Since the ∆G is negative, the reaction will be spontaneous. In the Exergonic reaction, the free energy release will occur, hence the total energy of the products will be less than that of the reactants and it does not require the need for external energy for the reaction to proceed. The exergonic reaction will lead to the conversion of complete reactants into products.

Question 14

Option 5 - Antiporters

They can bind two or more molecules and transport across a membrane in the opposite direction. Symporters are a type of transporters that can transport two or more molecules at a time in the same direction and Uniporters can transport only one type of molecule across the membrane. Dual transporter means the combination of two types of transporters that are present in a membrane, They can transport various materials across the membrane but they depend on two transporters. Channel pumps are examples of active transporters. They can pump certain materials across the membrane in a single direction against the concentration gradient using the ATP.
