The study of protein synthesis often uses a cell-free system where cells are ground with an abrasive to release the cell contents and then filtered to remove the abrasive. These mate- rials are added to the system, generating the indicated results: Materials Added Results Radioactive amino acids Radioactive protein produced Radioactive amino acids No radioactive protein produced and RNase (an RNA- digesting enzyme) What is the best interpretation of these observations?
Which of the following statements are correct about how the complex biological matrix of the cell may affect protein folding, stability and function (select all that appy)? A. ATP tends to "bounce" along the surfaces of many proteins without forming a stable complex B. Proteins make up approximately 30% of the total volume of the cytoplasm in a typical cell C. Compettition between drug molecules and metabolites in the cytoplasm may cause unexpected drug side effects not seen with individual proteins in solution. D. Large protein complexes move faster through the cytoplasm than small metabolites. E. Complex intercations between proteins in the cell may significantly destabilize a protein compared to the isolated protein in water

Both thiopental and pentobarbital have been used in the lethal injections. Pentobarbital has been preferred over thiopental, but it seems constantly to be in a shortage. There have been complains against the use of thiopental. Based on the chemical structure and interaction with the two main environments of a biological system (water and lipids) which one will get into the cell and distribute faster? Which one will stay longer into the system and for what reason? In your explanations please refer to the stuctures provided below. CHCH, CHCH,CH,CH, CH,CH, CHCH,CH,CH, CH, HN Thiopental Pentobarbital
Ammonia (NH3) is a weak base that under acidic conditions becomes protonated to the ammonium ion in the following reaction: NH3 + H+ → NH+4 NH3 freely permeates biological membranes, including those of lysosomes. The lysosome is a subcellular organelle with a pH of about 4.5–5.0; the pH of cytoplasm is about 7.0. What is the effect on the pH of the fluid content of lyso- somes when cells are exposed to ammonia? Note: Ammo- nium (NH4+) does not diffuse freely across membranes.
The image below represents a patch of membrane, in which there are embedded some proteins with sugars attached to them. Please answer these two questions: 1. Describe at least one function that these sugars may serve to this cell in the figure. 2. Describe how/where (in the cell) these sugars must have been attached to these membrane proteins.
