Cellular Communication and the Cell Cycle FRQ: a) Low extracellular pH activates TRPV1 through the binding of H + ions to TRPV1. Describe the properties, including the location, of the site of TRPV1 that allow H+ ions to bind. Describe the specific location in the cell where ATF3 protein is produced.

b) The pGoG protein is known to block the G1 to S transition in the cell cycle. Explain why this prevents mitosis from happening in the cell.

Complete the following statements about the functions of the digestive system.carbohydrates and fats are digested in secretes enzymes that aid in the digestion of carbohydrates, fats, and proteins.the secretes bile; bile is stored in undigested food is processed into feces in feces is then stored in until it is eliminated from the body via

Give an example of a trait that is controlled by more than one gene.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
