Which is a difference between a compound light microscope and a transmission electron microscope?
a. the compound light microscope can only view specimens in black and white, while the
transmission electron microscope has color.
b. the compound light microscope can view living things, but the transmission electron cannot.
c. the compound light microscope examines the surface of a cell, and the transmission electron
microscope examines internal parts of the cell.
d. the transmission electron microscope is used for dissections, while the compound light
microscope is not

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
