BY-PRODUCT OF GLYCOLYSIS
PYRUVIC ACID
THE MOLECULE THAT WILL REACT WITH KREB CYCLE IS?
ACETYL COENZYME-A
Pyruvate is Converted to?
Acetyl CoA
formation of acetyl coA
Krebs Cycle is discovered by?
Hans Krebs
the citric acid cycle takes place in the matrix of?
mitochondria
EIGHT STEPS OF KREB’S CYCLE
series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2
Citrate formula
oxaloacetate + acetyl CoA → citrate + CoA
• Citrate goes through a series of chemical transformations, losing ____ carboxyl group as CO2
two
How many ATP is formed (per acetyl group) by substrate- level phosphorylation
1 or one
CITRIC ACID CYCLE
In a single turn of the cycle, ___ carbons enter from acetyl CoA and ___ molecules of carbon dioxide are released;
two
How many molecules of NADH in a single turn of the krebs cycle?
three
How many molecules of FADH2 in a single turn of the krebs cycle?
one
How many molecules of ATP OR GTP produced in a single turn of the krebs cycle?
one
TOTAL BY-PRODUCTS OF KREB’S CYCLE
6 NADH, 4 CO2, 2 ATP, 2 FADH2
Oxidative phosphorylation
involves electron transport and chemiosmosis and requires an adequate supply of oxygen.
ELECTRON TRANSPORT CHAIN
The mitochondria has two membranes--the outer one and the inner membrane . The H+ which are brought to mitochondria accumulate between these two membranes.
The ETC happens in the
outer membrane of the mitochondria
NADH to NAD+ + H+
Complex I converts
converts FADH2 to FAD
Complex II
Converts 2H+ and ½ O2 to water
Complex IV
The total ATP produced in ETC is
32 ATP
Oxygen
is the final electron acceptor and it joins with the H + to produce H2O.
Chemiosmosis
the H+ diffuses back across the inner membrane through ATP synthase complexes, driving the synthesis of ATP.
ATP SYNTHASE
the H+ diffuses back across the inner membrane through ____ complexes, driving the synthesis of ATP.
