Answer:

They can speed up metabolic rate in the body.

Explanation:

Enzyme generaly lower activation energy of the substrate so that the rate of chemical reaction cam be increased.

This characteristics of enzymes makes them to be called organic catalysts.They are responsible for aiding fast completion of most biochemical activities in living organisms.

They usually react with specific substrates with their specific Active sites.

The x chromosome is found ________. the y chromosome is found ________. in both males and females; only in females only in males
elixir [45]

The answer is both in males and females; only in males. Males have one Y chromosome and one X chromosome, while females have two X chromosomes. In mammals, the Y chromosome controls a gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and other mammals also contain other genes needed for normal sperm production.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
