Question

Gly-Ser-Cys- Glu -Asp-Asn - Cys-Arg Write the peptide sequence shown above using single letters and the full names of the amino acids. Which amino acid is at N-terminus and which is at the C- terminus of the peptide? What is the charge on the peptide at pH 4.5? Name the peptide (using the amino acids in the sequence) 1. 2. 3. 4. Select the correct choice in the multiple choice questions below and explain why the other choices are incorrect. All of the following subcellular structures can be isolated essentially intact except: a. Endoplasmic reticulum b. Lysosomes C. Mitochondria d. Nuclei e. 5. Peroxisomes 6. Biological membranes are associated with all of the following except: a. b. c. d. e. Prevent free diffusion of ionic solutes Release of proteins when damaged Contain specific systems for the transport of uncharged molecules Sites for biochemical reactions Proteins and nucleic acids cross freely 7. The ion product of water a. Is independent of temperature b. Has a numerical value of 10'1 at 25°C c. Is the equilibrium constant for the reaction HOH

Explanation / Answer

1. GSCEDNCR

Full name are glycine, serine, cysteine, glumtamic acid, adpartic acid, asparagine, cysteine, arginine

2. Glycine is present at amino terminal whereas arginine is present at carboxylic terminal.

4. The name if the peptide is written by adding "yl" to the amino acid suffix.

Glycylserylcystylglutamylaspartamylssparagylasparamylcystyl argine.

Last amino acid name is written like as sucg

5. Endoplasmic reticulum can be extracted intact because they contain ribosomes attached with it. Hence, option

a is correct.

6. Biological membrane perform various task except they are not the sites of biological reaction. Because chemical reaction occur in cytoplasm.

7. The ionic product has value of 10 -14 at 25 degree Celsius .Hence, option b is correct .ionic product change with temperature and o

Oh. Hence, when calculated for 25 degree Celsius it value is 10 -14.
