Concept explainers
(a)
To determine: The other variable needs to known for calculating the net ecosystem production (NEP) if the NPP is known.
Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.
(b)
To determine: Why it is difficult to measure a variable that involves in net ecosystem production (NEP) ocean.
Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.

- Draw the structure of the anti-HIV drug AZT (zidovudine), which stops retro-viral DNAsynthesis. When AZT is taken up by cells, it is converted to AZT triphosphate. Explain how thiscompound could interfere with DNA synthesisarrow_forwardIn the mevalonate pathway, three acetyl-CoA are combined to give a C5 product, IPP.A. Write out a 5-step general acid/general base mechanism to explain how HMG-CoA isformed from 3 acetyl-CoA (Note: we are leaving out some details. The enzyme HMG-CoA actuallyuses its Cys residues to accept acetyl groups from 2 acetyl-CoA, making new thioesters and liberatingCoASH) B. Two NADPH and two H+ are required to form mevalonic acid from HMG-CoA. Circle the Hatoms that came from NADPH, and put a square around any H atoms that came from H+.C.
