That is very false. What about physical reactions? yeah. that's false
        
                    
             
        
        
        
Answer: A (ATP only) 
Explanation:
Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.
Answer is ATP only 
 
        
             
        
        
        
<span>Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes.</span>

They latch on to intruders and serve as signals to the immune system to attack the bacteria they have launched on to. After the Bacteria has been destroyed they also stay around and remember what that bacteria looked like so your body can try and stop that type of bacteria sooner and more effectively.
