For each molecule of glucose processed during glycolysis, the net yield is . 1. two molecules of NADH, two of ATP, and two of pyruvate2. two molecules of NAD , two of ATP, and two of pyruvate 3. two molecules of NAD , four of ATP, and two of pyruvate 4. two molecules of NADH, four of ATP, and two of pyruvate

1. two molecules of NADH, two of ATP, and two of pyruvate.

Explanation:

Glycolysis is defined as the breakdown of sugar which takes place in the cytoplasm. The various processes and enzymes involved are summarised in the Kreb's cycle.

Glycolysis is present in nearly all living organisms. Glucose is the source of almost all energy used by cells. Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.
