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). 
 
        
             
        
        
        
Answer:
A downhill
Explanation:
