There are four major groups of macromolecules. These include proteins, carbohydrates, lipids, and nucleic acids. Macromolecules are molecules constructed by attaching smaller molecules together into to one macromolecule that has specific properties and that may function as an independent unit.

For this discussion, pick one class of macromolecules and provide details about the structure of the compounds found in that class. Then choose an example from that class and describe one of its functions in a living organism. You may look in any part of the organism. For example, lipids are used by skin cells and neurons or nerve cells. Are their functions always the same in both instances?

Match the macromolecules to their function within cells Match each of the options above to the items below. 1. Carbohydrates 2.Lipids 3. Proteins 4. Nucleic Acids

How does catabolism of glucose from dietary carbohydrates link to fatty acid synthesis?

Choose one or more:

A. Catabolism of excess dietary carbohydrates raises the energy charge of the cell, which slows the flux of the citric acid cycle.

B. Glycolytic intermediates can be used as substrates for fatty acid and triacylglycerol synthesis.

C. Increased flux of the citric acid cycle produces NADH, which can be used for fatty acid synthesis.

D. Catabolism of excess dietary carbohydrates reduces fatty acid oxidation.

PCR was used to amplify a small region at the 5’ end of the coding region of a mutant allele in yeast. This region was sequenced, with the predicted RNA transcript given below and grouped in codons:

Grade 12 University Biology Strand in which it relates to?

How does it relate to this specific strand? Be specific in your answer.

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 40.0cm wide and 48.0cm high. The maximum safe pressure inside the vessel has been measured to be 5.10MPa.

For a certain reaction the vessel may contain up to 2.73kg of dinitrogen difluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius.

Round your answer to 3 significant digits.
