Answer from: jaelynnm

The biological function of penicillin primarily stems from the reactivity of the cyclic amide functional group also known as the β-lactam ring from the penicillin molecular structure. Attached is an image of the penicillin molecule and in red is the ring. This ring is the reactive portion because it has the ability to binding to the enzyme DD-transpeptidase, blocking it. This enzyme is important because it is involved in the synthesis of the bacterial cell wall.

Answer from: ana9340

The biological function of penicillin stems primarily from the reactivity of β-lactam ring (cyclic amide) functional group.

β-Lactam Ring:

It is the most important part of the penicillin structure. It is a cyclic amide functional group. This ring bind with enzyme DD-transpeptidase and block its function.The enzyme DD-transpeptidase is involed in bacterial cell wall synthesis.

Hence, we can conclude that the biological function of penicillin stems primarily from the reactivity of β-lactam ring (cyclic amide) functional group.

Answer from: Quest

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients: open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures: the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
