If a cell is restricted to only using only peptides and proteins for its catabolism, what molecule is released from the cell as a byproduct? Why?
Homework Answers
If a cell is able to utilize only
peptides and proteins, a greater amount of nitrogen is produced in
the form of ammonia.
Proteins are composed of amino acids. They are used as an energy
source under severe starvation conditions.
Their entry into catabolism first requires deamination to produce a
carbon skeleton that can enter the catabolic pathway.
This deamination produces Ammonia.
Proteins --------> Amino acids --------> Keto acids +
Ammonia

Q1: What are catabolism and anabolism (4 marks)? Q2: Under aerobic respiration, a molecule glucose is oxidized to generate 36 ATPs in eukaryote cell while 38 ATPs in prokaryote cell. Explain how this difference occurred (6 marks). Q3: Why aerobic respiration could produce more energy (ATP molecules) than anaerobic respiration and fermentation? By using glucose as the substrate, illustrate how ATP molecules are being produced in each case (15 marks). Q4: "Most microbes use carbohydrate (glucose) as the energy sources...

The catabolism of one molecule of glucose results in the production of about 38 ATP’s. A new mutation has been discovered that results in the production of only 19 ATP^ prime s from one molecule of glucose. This new mutation has been narrowed down to something within glycolysis. What within glycolysis can account for the production of only half the number of ATP’s? Explain.

Within a prokaryotic cell, bacteria, you will find peptidoglycan. This is a component only found in bacteria. The role of this compound, peptidoglycan, is to give bacteria its rigid structure within the cell wall. This is what protects certain substances from entering the bacteria, this sturdy wall provides support and strength to the bacteria. Peptidoglycan is composed of, to simplify, sugar and proteins that allow the cell wall of bacteria to be strong and bendy. Another reasons why peptidoglycan is...

E. coli makes curli fibers on its cell surface that are bacterial amyloid proteins. These curli are used as models to study eukaryotic amyloid proteins in human disease such as Alzheimer's. In E. coli the protein used to secrete curli fibers is CsgG. Using NCBI, search for this protein - "csgG E. coli. K12 W3110" in the protein database, and select the RefSeq protein entry. From the right-hand side of the protein page, select 'Run BLAST'. Select 'Escherichia coli (taxid:562)'...
