Give one way in which glycolysis and the krebs cycle are similar

Both glycolysis and Krebs cycle produce a net of 2 ATP each at the end of their cycles. Both cycles also produce reduced coenzymes for electron transport.  They produce NADHs (the only difference is that Krebs produces 6NADHs while glysolysis produces 2NADHs).

the awnser is d i think

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
