What is the total number of atps produced by cellualar metabolism (per glucose molecule)?

38 ATP

Explanation:

One molecule of glucose on complete breakdown yields 38 ATP.  The break up of APT production at different steps of cellular respiration is given below:  

Each NADH releases 3 ATP and each FADH₂ releases 2 ATP. Altogether 10 NADH is produced which yield 30 ATP and 2 FADH₂ yields 4 ATP.

Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

weathering is the answer.
