Answer:
The nucleic acid DNA is an organic compound. DNA is made up of repeating subunits called nucleotides . Each DNA molecule consists of 2 long chains of nucleotides. A DNA nucleotide has three parts: a sugar molecule called deoxyribose ; a phosphate group, and a molecule that is referred to as a nitrogenous base because it contains nitrogen atoms. The deoxyribose sugar and the phosphate group are identical in all DNA nucleotides. However, the nitrogenous base may be any one of 4 different kinds. The four nitrogenous bases found in DNA nucleotides are adenine, thymine, cytosine, and guanine. The two strands of a DNA molecule are held together by hydrogen bonds.

The answer is A. Chemical Energy from broken bonds is transformed into mechanical energy for muscels
Answer:
phosphofructokinase
Explanation:
Phosphofructokinase 1, also known as PFK-1, is the second glycolysis regulatory enzyme and its main regulatory point. Therefore we can state that this enzyme is exerts the greatest control over glycolysis.
Phosphofrutokinase is an allosteric enzyme belonging to the phosphotransferase family that catalyzes a phosphorylation: the conversion of fructose-6-phosphate and ATP into fructose-1,6-bisphosphate and ADP, a key step in regulating and limiting glycolysis rate in response to the cell's energy needs through the allosteric inhibition process
