Cellular Respiration
reduction; oxidation; transferring electrons from one molecule to another molecule, from the donor to the receptor
REDOX
oxidizes glucose molecules through glycolysis, the Krebs cycle, and oxidative phosphorylation to produce ATP
cellular respiration
breaking a glucose molecule; has a 6 carbon molecule;
glycolysis
combine Acetyl CoA2 carbon molecule with oxaloacetate which is a four carbon molecule and the product of that which is called citrate; break into other carbon molecules
Citric Acid Cycle
three successive steps in Aerobic
1. glycolysis
2. the citric acid cycle
3. electron transport
What happens with the donor in redox?
its oxidized
these power the proton (H+) pumps in the electron transport chain
what are falling electrons or high energy electrons?
what are the three phases of glycolysis?
Energy consuming phase, Coupling of phosphorylation with oxidation 2 (3) carbon molecules, energy releasing phase (end two pyruvate molecules)
1. drop off high energy electrons (NADH) into the first protein in the electron transport chain; 2. as proteins go protein to protein they are losing energy; 3. use energy as they pass through electron at the end of etc (low energy electrons); 4. get rid of via oxygen/hydrogen forms water
Oxidative Phosphorylation & ETC
a metabolic pathway that takes place in the cytoplasm
glycolysis
what happens with the receptor in redox?
receptor is reduced
high energy electrons; nicotinamide adenine dinucleotide) is a coenzyme made from a vitamin niacin (B3)
NADH
Pyruvate oxidation
enzyme that synthesizes ATP which means from our parts adenosine diphosphate and free phosphate groups
ATP synthase
a metabolic pathway that occurs in the mitochondrial cortex
citric acid cycle
remove electrons that are holding it together when you remove electrons your oxidizing; when we oxidize glucose were left with carbon dioxide as a waste product
cellular respiration during redox
ATP
In pyruvate oxidation there is an attachment of coenzyme A to 2 carbon molecule called
Acetate and that forms what's called Acetyl CoA
when NADH gives its H's to pyruvate lactic acid is created; RBCS don't have mitochondria; use only lactic acid pathway; occurs in skeletal regularly & heart muscle when oxygen supply falls below critical level only rarely
Lactic Acid Fermentation
a process that occurs in the mitochondrial cristae
electron transport
what happens if you don't have anywhere to put electrons can you still make ATP?
No, which means cellular work stops
what are the three steps of cellular respiration?
1. Glycolysis
2. Pyruvate Oxidation & Citric Acid Cycle
3. Oxidative Phosphorylation
this compound is involved in cellular respiration, but it is also a common substrate for energy & synthetic pathways
what is Acetyl CoA?
because of the involvement of oxygen, the metabolic pathway that converts molecules such as glucose or fatty acid to carbon dioxide and water (transferring some of the energy to ATP)
Aerobic
means that oxygen is not being used in the process. this occurs in the skeletal muscles and heart when the ratio of oxygen supply to oxygen need falls below a critical level
Anaerobic
