uranium lasts roughly 6 -7 years
I think it is either A or B but I am not sure. I know a catalyst increases the rate of a chemical reaction but I don't think it is B because I dont believe that an enzyme is shaped to interact with certain molecules. I would go with A or C. The choice is yours.
A shark because its more cartilage than actual bone.
Answer:
The statement is true since one of the main functions of the enzyme is to lower the activation energy so that a chemical reaction to proceed.
Explanation:
Enzymes are specialized protein molecules that contribute to faster chemical reactions. One of the functional characteristics of an enzyme is that it reduces the activation energy for a reaction to occur.
Activation energy is the amount of net energy required for a reaction to occur. By lowering the activation energy, a reaction occurs faster, which is achieved with a biocatalyst such as enzyme.
