force times distance

Question 48

Soccer (assuming field player) is a sport which is 90% aerobic.

True

False

Question 50

Glucose is necessary for fatty acid oxidation because...

its derivative, pyruvate, is condensated with carbonic acid to form oxaloacetate, which in turn is a necessary carbon compound in the citric acid cycle

it is needed to convert fatty acids to fatty acyl-CoA which in turn is oxidized to acetyl CoA

glucose is decarboxylated into cytochrome oxidase which is a necessary intermediate in the citric acid cycle

its derivative, acetyl CoA, is condensated with carbonic acid to form lactase, which in turn is a necessary carbon compound in the citric acid cycle

Question 51

In aerobic ATP production, the role of oxygen is to...

to keep the electron transport chain operational

to accept electrons from the 3rd cytochrome and thereby oxidizing it so it can accept new electrons

act as a oxidizing agent by accepting electrons from the electron transport chain and combining with hydrogen ions (protons)

all of the above

Question 52

The primary purpose of the citric acid cycle is...

aerobic glycolysis

gluconeogenesis using lactate

the decarboxylation of carbon compounds to produce NADH.

the shuttling of hydrogen ions through the inner mitochondrial membrane

Question 55

Which of the following is the best predictor of marathon running performance?

A.

Maximal rate of pyruvate oxidation

B.

Maximal rate of lactate formation

C.

Amount of adipose tissue triglycerides

D.

Pre-race blood glucose concentration

Homework Answers

Answer #1

48) Soccer (assuming field player) is a sport which is 90% aerobic- true

energy derived from the aerobic metabolism is used for 90% of the movements of soccer players and is a prerequisite for this modality.

50)Glucose is necessary for fatty acid oxidation because...

it derivative, pyruvate, is condensated with carbonic acid to form oxaloacetate, which in turn is a necessary carbon compound in the citric acid cycle

51) In aerobic ATP production, the role of oxygen is to...all the above

52) The primary purpose of citric acid cycle is aerobic glycolysis.

55) B- Maximal rate of lactate formation

lactate threshhold is considered to be a good predictor of endurance performance .as exercise intensity increases blood lactate levels rise .

Which is true about how are cells use oxygen? A. When oxygen is present pyruvate is converted to lactate which enters the citric acid cycle. The reduced coenzymes donate hydrogen ions and high energy electrons to the electron transport chain, and oxygen acts as the final acceptor of hydrogen ions and low energy electrons after the hydrogen ions have passed through ATP synthase. B. When oxygen is present pyruvate is converted to Acetyl CoA which enters the citric acid cycle....

6. Which of the four stages of respiration does NOT take place in mitochondria A. pyruvate processing B. glycolysis C. Citric acid cycle D. electron transport and oxidative phosphorylation 7. The citric acid cycle is a set of sequential reactions where 2 carbon atoms from Acetyl CoA (that derives from a glucose molecule) are coupled to a 4 carbon molecule. The carbon atoms from Acetyl CoA are released as CO2. Redox reactions and phosphorylation reactions are used to harvest energy...

1. Aspartate is metabolized to oxaloacetate, which we know via gluconeogenesis can be used to generate PEP. Assuming the PEP then proceeds to pyruvate and acetyl CoA and enters the citric acid cycle, how much ATP could be generated from the complete oxidation of Aspartate if we assume 1 NADH produces 3 ATP, 1 FADH2 produces 2 ATP, and GTP or ATP are equivalent (1GTP=1ATP). (Also ignore the “cost” of Nitrogen removal; don’t consider the urea cycle) 2. True or...
