Which of the following best explains the chemical nature of the substrate as it relates to the enzyme's active site and functioning? A) The shape and charge of the substrate need to match enzyme active site for binding, activation, and catalysis.
B) The pH of the substrate must be compatible with an enzymes active site for binding, activation, and catalysis
C) The substrate and enzyme must have identical bonds for binding, activation and catalysis to occur
D) The size of the substrate needs to match an enzyme active site for binding, activation and catalysis

What are the doorways into and out of cells, attached to the membrane, and built in the rough er.

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.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
