Answer:
They lower the activation energy of the reaction
Explanation:
Enzymes are proteinous biochemical molecules that serve as catalyst in living systems. They speed up the rate of biochemical reactions by lowering the activation energy of the reaction they are involved in.
As this question describes, enzymes possess an active site, which the substrate binds to yield products. The enzymes make the reaction faster by reducing the activation energy of the reaction, which is the energy needed to start a reaction.
The answer is C) 100 units of energy because of the 10% rule in biology! Hope this helps you~
Answer: The correct answer is A) Fertilization.
Fertilization is a process or event of fusion of two gametes ( also called reproductive cells that are haploid) that forms zygote, which is diploid cell. It is the first event in the formation of new individual.
The two haploid gametes are sperm ( male gamete) and egg ( female gamete), which are formed through spermatogenesis and ovulation respectively.
Thus, fertilization is the process that joins two haploid cells to form a diploid zygote.
Answer:
The primary difference between repressible and inducible systems is the result that occurs when the effector molecule binds to the repressor. ... Thus, for the trp operon , the addition of tryptophan (the effector molecule) to the E. coli environment shuts off the system because the repressors binds at the operator.
Explanation:
Acidity is determined using a pH indicator
