• Some proteins are synthesized on free ribosomes in the cytosol, while others are synthesized on ribosomes attached to the ER. Discuss, in general terms, the different fates of these two groups of proteins.
Homework Answers
Proteins are synthesized by ribosomes that are either attached to the endoplasmic reticulum or free ribosomes in the cytoplasm of the cell. Those proteins that are to be incorporated into the intracellular organelles like nucleus, mitochondria, chloroplasts and peroxisomes are made in the free ribosomes and released into the cytoplasm once their translation process is complete. The proteins that are destined to be secreted out of the cell like enzymes, hormones etc. are made in the rough endoplasmic reticulum.

Determine whether the following classes of proteins are synthesized on free ribosomes or ER docked ribosomes. a) Single-pass membrane proteins b) Multi-pass membrane proteins c) Peripheral membrane proteins (on the cytosolic side) d) Peripheral membrane proteins (on the luminal side) e) Peripheral membrane proteins (on the extracellular side) f) Fatty acid-anchored membrane proteins g) GPI- anchored membrane proteins - Where would a protein likely go if you were to remove a characteristic hydrophobic membrane spanning domain?

In the process of translation, mRNA attaches to ribosomes DNA is replicated proteins are synthesized RNA is synthesized QUESTION 11 What does it mean when we say the genetic code is unambiguous? More than one codon can specify the addition of the same amino acid. The genetic code is different for different domains of organisms. Each codon can specify the addition of only one amino acid. The genetic code is universal (the same for all organisms).

1. (1.5 pts) Entering the ER: Translocation of proteins across the membrane of the ER is usually studied using microsomes (vesicles made from rough endoplasmic reticulum. Microsomes of the rough ER carry ribosomes attached to their outer surface. Translocation of proteins across the microsomal membrane can be assessed by several experimental criteria: (1) the newly synthesized protein is protected from added proteases, but not when detergents are present to solubilize the protecting lipid bilayer; (2) the...

Some amino acids such as Ile, Met, and Leu have nonpolar, aliphatic radical groups, while others such as Ser, Cys, Glu, Pro, Asn, and Thr have polar uncharged radical groups. Where in proteins would you expect to find amino acids such as Ile, Met, and Leu but not amino acids such as Ser, Cys, Glu, Pro, Asn and Thr? A.on an outside surface interacting with water B.folded inside a central, core region that does not interact with water C.not within...

2. Proteins degradation provides free amino acids, which may be further degraded by deamination and transamination in order to synthesis new compounds, produce energy, or eliminate waste. Provide a brief description for each of the possible fates of free amino acids with specific reference to biochemical reactions and state how the products of these reactions may are utilized. 3. Consider the amount the ATP yield from two different 6-carbon biomolecules: fructose and caproic acid. With specific reference to the catabolic...

1) Some people group XSS attacks with XSRF attacks, while others think they should be considered separate. Make an argument that they are different and do this with an example of an attack under each (illustrating their differences). 2) Suppose I want to do a XSS attack that executes through someone’s brower, but I know the server blacklists the string Dogs as well as the word script. Describe at least two distinct ways to bypass this filter and give me...

Some states require corporations to issue par value stock, while others do not have this requirement. If there is no par value assigned to stock, it is known as stated value stock that is assigned a "stated value" per share. In this case, if a person invests $100,000 cash into a newly created corporation in exchange for 1,000 shares of $100 stated value common stock, the corporation records this transaction in their general ledger accounts as follows - Debit Cash...
