Glucose molecules provide energy to power the swimming motion of sperm. in this example, the sperm are changing

chemical energy into kinetic energy
chemical energy into potential energy
kinetic energy into potential energy
kinetic energy into chemical energy
none of the above

The sperm are changing chemical energy into kinetic energy.

Chemical energy is defined as the chemical substance’s potential to undergo a transformation through a chemical reaction. So, this type of energy can be transformed to other forms of energy by a chemical reaction.

Kinetic energy, on the other hand, is the energy that an object (structure) possesses due to its motion.

So, in the example above, chemical energy of the glucose is used (by breaking the bonds of this molecule through the chemical reaction) for the formation of sperm’s kinetic energy (necessary for movement).

the answer is 100% density i've answered this question before and done the quiz myself.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
