Cellular Respiration Exercise
What is the net result of one glucose molecule going through the Krebs cycle?
All options
Which parameters could you use to measure the effect of exercise on cellular respiration in mice?
All options
After glycolysis, the pyruvate molecules can follow two different metabolic routes aerobic and anaerobic respiration. What is the main difference between these?
Anaerobic respiration does not need oxygen to occur and anaerobic respiration does
What action would you recommend to the point guard?
Drink a maltose sports drink
The first step of glycolysis consumes energy. Two high energy ATP molecules phosphorylate glucose. How do you ATP molecules store energy?
High energy bonds between phosphate groups
So in summary, glycolysis breaks down glucose into two pyruvate molecules. How many carbon atoms does one molecule of pyruvate contain?
Three carbon atoms
What is the ATP yield per each molecule of glucose under low oxygen conditions?
To ATP molecules from glycolysis
Metabolism can be divided into catabolic and anabolic reactions how are these connected?
Catabolic reactions generate energy that anabolic reactions use
Why is the Krebs cycle so important if it only produces two ATP molecules?
It produces reducing agents for the electron transport chain
Which experiment would you perform to test what happens under extreme exercise conditions?
Make the mouse run at high high speed with low oxygen availability
What is oxygen used for in cellular respiration?
Oxygen is The last electron acceptor in the oxidation of electron carriers
What two processes are coupled throughout the ETC that together make up oxidative phosphorylation?
The oxidation of electron carriers and the phosphorylation of ADP
