The amount of energy needed for a reaction to take place is the activation energy. enzymes can lower the activation energy of a chemical reaction. which of the following describes a way that this could happen? question 9 options: the enzyme distributes atp to cells and then is destroyed. more substrate is added by the enzyme. molecules can be brought together so they will bond more easily. the enzyme separates molecules from each other. save

The enzyme separates molecules from each other.

Explanation:

Activation energy is an amount of energy that "pushes" the enzyme reaction to take place. The higher the value of this energy, the slower the enzymatic reaction will take place, so some enzymes can cause the activation energy to decrease, in order to accelerate the enzymatic process.

Generally, enzymes decrease the activation energy by modifying the physical structure of the molecule, separating some parts, or leaving the bonds weakened so that it is possible to break that molecule more easily. Enzymes can also participate in the reaction to reduce the activation energy.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
