Electron Transport Chain

The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell u…

Metabolism

Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unl…

Cellular Respiration

Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chem…

Question

Hamsters love to run exercise wheels. Prolonged running at a high rate of speed requires ATP. Coulda hamster with a defective gene for the enzyme lactate dehydrogenase meet the extra ATP demand forprolonged, fast wheel-running by maintaining a high rate of glycolysis? Why or why not?

-No, not enough NADH can be regenerated for glycolysis to continue at a high rate

-No, the defective gene will cause a rapid decline in pH in the muscles used for running

-Both A and B

-Neither A nor B

Which of the following statements is correct?

-The ketohexoses have fewer chiral carbon atoms than the aldohexoses

-The reaction between one molecule of alcohol and one molecule aldehyde yields an acetal

-Both A and B

-Neither A nor B

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
