The category of organic molecules that is correctly matched with one of its functions is (D) proteins – speed up chemical reactions.
Proteins are made up of amino acids and they serve a variety of cellular functions. These organic molecules also function as enzymes as well as hormones. Enzymes are proteins which act as biocatalysts and increase the rate of chemical reactions.
Carbohydrates are the macromolecules with the general formula (CH₂O)ₙ, where 'n' denotes the number of carbon atoms in the molecule. Their main function is to provide immediate energy to the body.
Lipids are non-polar organic molecules. They are hydrophobic in nature and are utilized for long-term energy storage by the cell. Nucleic acids are responsible for transmitting the genetic information from one generation to another.

Answer:
Neurotransmitters
Explanation:
Examples of neurotransmitter are acetylcholine, epinephrine, dopamine, GABA, serotonin, and etcetera. They are released from synaptic vesicles in the presynaptic membrane. They then diffuse through the synaptic cleft or neuromuscular junctions and bind to their receptors on the postsynaptic membrane and invoke an impulse.
The statement: Fertilization usually takes place in the fallopian tube is True
The fallopian tube links the ovary to the womb/uterus. So therefore, the fertilization of an egg by a sperm occurs in the fallopian tube
- As many as 50 percent of zygotes do not survive the first two weeks is also True
The zygote is formed as a result of the fusion between sperm and egg
During the period of the fetus, the most rapid prenatal changes take place. True
<h3>What is fertilization? </h3>
This the process which occurs as a result be of the union of sperm and egg which fuses to form zygote
