The oxidation of glucose into pyruvate is a process known as__________.
What is the energy released during glycolysis used for?
(1) What is the first step of glycolysis?
(2) What happens to the glucose and ATP after the Phosphate is added
(3) What happens to the 6 carbon sugar diphosphate (di=two phosphate)?
(4a) What happens to get the 3 carbon molecule to pyruvate?
(4b) What happens when electrons are transferred from PYRUVATE to coenzyme NAD+?
(5a) What happens to the pyruvate under aerobic conditions?
(5b) What happens to the pyruvate under anaerobic conditions?

Answers
_oxidation_ of Glucose into _pyruvate__
Cellular respiration
Glycolysis (series of steps)
ATP currency of life
(1) addition of two phosphates to the glucose at the expense of two molecules of ATP
(2) The glucose -- 6 carbon sugar diphosphate molecule and 2 low energy adenosine diphosphates (ADP)
(3) it splits into two 3-carbon molecules (3 carbon sugar phosphate)
(4a) electron transport chain
(4b) NADH and ATP formed
(5a) further oxidized to yeild more ATP
(5b) Converted into lactic acid (think muscles)
