Answer:
Olfactory system
Explanation:
In an olfactory system, odor molecules are perceived by the olfactory receptors. These odor molecules are nothing but the chemicals which are then transduced as chemical signals into the electrical signals and sent to the brain. The brain perceives these electrical signals as smell.
The odorant particles bind to the specific receptors located at cilia which then signal through the G protein Gαolf which then activate adenylate cyclase. Adenylate cyclase leads to cAMP production which then open a cyclic nucleotide-gated ion channel through which both sodium and calcium ion entern into the cell. Calcium ion then activates chloride channels and thereby causing transduction of electrical signal
Answer: Protiens help provide structural support for our metabolism, and they can act as enzymes, carriers, or hormones to help us. They provide growth and maintenence and also act as messengers for our brain. They bolster our immune system and also transport/store nutrients. Basically, they do a whole lot!
Explanation:
Fermentation Occurs In The Cytoplasm
The answer is <span>DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.
DNA polymerase performs the polymerization of DNA. It adds nucleotides to the new DNA strand according to the base-pairing rules. This means that adenine binds to thymine and guanine binds to cytosine. The DNA polymerase is important enzyme responsible for accurate DNA replication.
Choice 2 is incorrect because DNA does not contain uracil.
Choice 3 is incorrect because helicase untwists DNA.</span>
