Cellular Resp 4

Question 1

Products of kerbs cycle
cycle runs twice for each glucose and ones per each pyruvate
Per pyruvate
per glucose

Answer 1

3 CO2 (waste), 1 ATP, 4 NADH, 1 FADH2

6 CO2 (waste), 2 ATP, 8 NADH, 2 FADH2

Question 2

Oxidative Phosphorylation combines the ETC (electron transport chain) and chemiosmosis
-occurs where
-what moves from the matrix and where does it go
-electrons are pulled to what
-reaxtion
-energy from that rection pumps protons where

why does oxygen bind with these free protons

Answer 2

-inner membrane (cristae)
-NADH and FADH2 move from matrix to inner membrane
-pulled to stronger electron acceptors in a series of Redox reactions (oxygen is final e- acceptor)
-2e- and 2h+ and 1/2 o2 forms h2o
-into the intermembrane space

to maintain the hydrogen garident and formation of water

Question 3

Chemiosmosis
-its how _____
-what is it
-protons build up where and why
-they diffuse back where and why
-energy from protons allows for what

how much ATP is produced per electron carrying molecule
-NADH from glycolysis
-NADH from krebs cycle
-FADH2 from Krebs cycle

Answer 3

-how an H+ garident is used to make ATP
-movement of ions across a selectivley permeable membrane down their electrochemical gradient, relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular resp
-build up in small intermmembrane space because of ETC
-back to matrix through ATP synthase
-energy from protons moving through synthase allows fr phosphorylation of ADP to make ATP
