Cellular Respiration OAT Exam 100% Correct AnswersCellular respiration
is the process in which cells make ATP from energy. Energy is extracted from
energy-rich glucose to form ATP from ADP and P i .
chemical equation for cellular respiration
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy
C6H12O6
is glucose
aerobic respiration
Cellular respiration in the presence of O2
Aerobic respiration is divided into three components
glycolysis, the Krebs cycle, and oxidative phosphorylation
Glycolysis
is the breakdown, lysis, of glucose, glyco, to pyruvate, or pyruvic acid.
Steps of Glycolysis
1. 2 ATP are added
2. 2 NADH are produced
3. 4 ATP are produced
4. 2 pyruvate are formed
, In summary, glycolysis takes 1 glucose and converts it into 2 pyruvate, 2 NADH, and a
net of 2 ATP-made 4 ATP, but used 2 ATP. The process occurs in the cytosol.
Where does Glycolysis take place in?
The process takes place in the cytosol.
Why Does the kreb Cyles have x2?
The Krebs cycle explains what happens to pyruvate, that is the end product of
glycolysis. As the Krebs cycle is explained for 1 pyruvate, keep in mind that the
glycolysis produced 2 pyruvate.
Steps of Kreb Cyle
1. Pyruvate to acetyl CoA.
2. Krebs Cycle: 3 NADH, 1 FADH 2, 1 ATP, CO 2. Krebs cycle is initiated when the acetyl
CoA joins to OAA, oxaloacetate, to produce citrate.
Oxidative phosphorylation
is the process by which ATP is extracted from NADH and FADH
In the Electron Transport Chain,how many ATP does FADH2 and NADH make?
NADH gives electrons that have enough energy to make about 3 ATP, while FADH2
makes about 2 ATP
ncytochrome c
Cytochrome c is a heme protein that is localized in the compartment between the inner
and outer mitochondrial membranes where it functions to transfer electrons between
complex III and complex IV of the respiratory chain
How many ATP can theoretically be made from the energy released from the breakdown
of 1 glucose?
