Answer:
Aerobic respiration;this is the process of breaking down of glucose  <u>with Oxygen</u> to generate energy  as ATPs in living cells
Location- Matrix  and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water  i<u>n the presence of  sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast 
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs
