Cellular respiration (Glycolysis\aerobic respiration) Flashcards
Memorize for tests\quiz
What is anaerobic respiration?
A process in cellular respiration that does not require oxygen
What is aerobic respiration?
A process in cellular respiration that requires oxygen
What are the three stages of glycolysis?
Glycolysis, Citric acid cycle (Krebs cycle), Electron transport chain
What are the reactants in cellular respiration?
Glucose and oxygen
What are the products of cellular respiration?
CO2, H2O, and ATP
What is the chemical equation for cellular respiration
C6 H12 O6+O2= CO2 & H2O & ATP
What are the two stages of cellular respiration called?
Glycolysis and anaerobic respiration or fermentation
What are the two types of fermentation that can take place at the end of cellular respiration
Lactic acid fermentation and alcohol fermentation
Where is the most ATP made?
The Electron transport chain
When H+ ions move through the ATP synthase it produces what product of cellular respiration
ATP
What role does oxygen play in the E.T.C.
Oxygen molecules attach to H+ molecules in the matrix and used electrons from the E.T.C. cycle to make water.
Electrons help ________ enter the inner membrane of the mitochondria
Hydrogen+
What happens in glycolysis
Glucose is broken down into 2 pyruvate with the help of 2 ATP, 2 NAD+, 2 ADP, and 2 P
What happens to NAD+ at the end of glycolysis?
It gets reduced to NADH
How many ATP is yeilded from glycolysis
4 ATP (net gain of 2 ATP
What does glycolysis mean?
Glucose breakdown
Where does glycolysis take place
cytosol
What happens in the first, then second phase of glycolysis
In the first phase the glucose is broken down to glyceraldehyde -3- phosphate, and in the second phase is broken down into pyruvate.
How is acetyl CoA made
2 pyruvate are oxidized by NAD+ this reaction also produces Co2 and NADH
What happens in the krebs cycle ((citric acid cycle) before ATP is produced)
Acetyl CoA links up with oxaloacetate making citric acid, it then gets oxidozed by NAD+ breaking the citric acid to a 5 carbon molecule, this molecule is broken down once again so it can accept a phosphate and ADP to make 1 ATP.
What happens in the krebs ((citric acid cycle) after ATP is produced)
FAD comes and oxidizes the carbon molecule further and turns into FADH2, Another NAD+ molecule does the same. Now the carbon is oxaloacetate once again.
Where does the NADH and FADH2 go after the krebs cyle
Theelectron transport chain
What happens in the electron trandport chain (before ATP synthase)
Electron carriers NADH and FADH2 drop off electrons to the inter membrane, the energy from the electrons allows hydrogen ions to make theri way into the inter membrane. The electrons are then passed along the iner membrane until oxygen and hydrogen from the matrix combine with them to make H2O.
What happens in the electron trandport chain (after ATP synthase)
Hydrogen ions from the inter membrane make their way through the ATP synthase. The ATP synthase turns like a turbine creating more energy and allows ADP and a phosphate to combine. causing ATP to be produced
