Chapter: 3 Worksheet: 2

Cellular respiration energy(_____ ATP) produced to make ATP, and a NET ATP of ________.

GLUCOSE into ___________ (how we derive energy from carbohydrates we eat)

The Progression of Respiration:

1)glycolysis(glucose) located in the _________= substrate-level phosphorylation,

-Makes ______ATP and _________for use in mitochondria IF oxygen available;

2)intermediate stage(pyruvate) = 'prepares' pyruvate for citric acid cycle and serves as the link between glycolysis and c.a. cycle;

3)citric acid cycle = requires oxygen, substrate-level ____________________,

_____(hint: #) 'turns' per glucose molecule yields :

____ ATP, ___ NADH, ____ FADH2,

- after this glucose is digested and the carbons are exhaled as _______ gas;

4)**electron transport chain** = oxidative ______________________.

-Electrons are transferred from NADH and FADH2 membrane channels that pump _____+ out of cell,

-final electron acceptor is _________,

-H+ concentration gradient OUTSIDE / INSIDE cell pushes H+ OUTSIDE / INSIDE cell. (ex. like water over dam)

-Energy from H+ movement is used to add ___rd phosphate to ______ making ATP,

***MOST EFFICIENTSTEP:

- ______ ATP produced; NET ATP PRODUCED is ________***

EQUATION: Glucose + O2 CO2 + H2O + ENERGY

- Rememeber: GLUCOSE is OXYDIZED, and OXYGEN is REDUCED.

- * Key words: Electron EXCHANGE CHAIN…Glucose GIVES H+ away, and O2 TAKES (accepts) it.
