a)During β-oxidation of long-chain fatty acyl CoA derivatives, energy is released. The following statements describe the way in which the energy is released and made available.NADH and FADH2 result from the entry of acetyl CoA into the TCA cycle and yield ATP via the electron transport chain.True/False?

b)During β-oxidation of long-chain fatty acyl CoA derivatives, energy is released. The following statements describe the way in which the energy is released and made available.ATP is produced by substrate-level phosphorylation.True/False?

c)During β-oxidation of long-chain fatty acyl CoA derivatives, energy is released. The following statements describe the way in which the energy is released and made available.NADPH is produced which yields ATP via the electron transport chain.True/False?

d)During β-oxidation of long-chain fatty acyl CoA derivatives, energy is released. The following statements describe the way in which the energy is released and made available.Both NADH and FADH2 are produced which yield ATP via the electron transport chain.True/False?

e)The breakdown of the fatty acid CH3CH2CH2CH2CH2CH2CH2CH2COOH via the β-oxidation pathway would:

yield three moles acetyl units and one mol propionyl units.True/False?

f)The breakdown of the fatty acid CH3CH2CH2CH2CH2CH2CH2CH2COOH via the β-oxidation pathway would:yield three moles propionyl units.True/False?

g)The breakdown of the fatty acid CH3CH2CH2CH2CH2CH2CH2CH2COOH via the β-oxidation pathway would:yield four moles acetyl units and one mol propionyl units. True/False?

Solutions

Expert Solution

A) TRUE Beta oxidation is a catabolic process by which fatty acid molecule is broken down to generate acetyl-coA which enters the citric acid cycle. and NADH and FADH2 used in electron transport chain and yeild ATP.

B) FALSE, Because substrate-level phosphorylation produced ADP is converted to ATP by the direct transfer of a phosphate group. ATP is produced by oxidative phosphorylation in beta oxidation.

C) FALSE, NADPH mainly involved in anabolic process but beta oxidation is a catabolic process. IN Beta oxidation NADH and FADH2 used in electron transport chain which yeild ATP.

D) TRUE, Both NADH and FADH2 are produced which yield ATP via the electron transport chain. This process is called oxidative phosphorylation.

E) TRUE, During beta oxidation of odd chain fatty acid the last products are an acetyl CO-A and propionyl units. when beta oxidation of 9 carbon fatty acid occurs it produces 3 mole of acetyl co-A and one moles of propionyl units.

F) FALSE , one moles of propionyl units and Acetyl co-A is produced by beta oxidation. because it enters into TCA cycle and operate it.

G) FALSE, Because here three mole of acetyl co-A produced by beta oxidation of 9 carbon fatty acid.

Where in the cell do these pathways occur? Next, explain how reduced oxygen slows each pathway(s) identified. Once oxygen is no longer limiting, energy production resumes. Explain how the concentration of ATP increases with the availability of oxygen (detailed pathways and structures are NOT required). Next explain in detail how ATP...

During an earthquake, seismic energy is released and it can travel long distance from source (location of the earthquake) to a seismic station. Path taken by a wave is similar to a ray (line with an arrow) which travels through the earth and arrives at a station. In the last assignment, we look into a case where earthquake is right beneath the station. In this assignment, we are going to investigate a case in which the station is far away...
