Key event 1: chemical energy is invested. key event 2: high-energy electrons stored in bonds are released and transferred with protons to available electron carriers. key event 3: atp is made by phosphorylation. during glycolysis, how many nadh molecules are produced per glucose molecule? two four one

During Glycolysis 2 molecules of NADH are formed.

Explanation:

When the glycolytic intermediate glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate by the catalytic activity of glyceraldehyde -3-phosphate dehydrogenase at that time 2 molecules of NAD+ undergo reduction to form 2 molecules of NADH.

   The so formed NADH enters into the electron transport chain to generate ATP.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
