Which of the following statements are true? (This is a multi-select question, select all that apply).Carbohydrates serve mainly for short-term energy storage; TAGs serve mainlyfor long-term energy storage.Both carbohydrates and TAGS serve other important roles, such as in molecularrecognition.Both carbohydrates and TAGS serve important roles as second messengers.Carbohydrates can be used to produce ATP much more quickly than TAGS can.TAGS are a much more efficient way to store energy (you can get more ATP on a"per weight" basis).

The amino acid sequence (primary structure) and 3D shape (tertiary structure) of the rhodopsin has been determined and the various protein domains have also been identified with precision (see figures below). The red arrow indicates the amino acid lysin (K) that binds to the oxygen of the retinol (indicated by the blue arrow). The purple arrow indicates the retinal bound to the rhodopsin. In healthy individuals, retinal is abundant and can binds to the rhodopsin, making it functional (light-sensitive).

Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit ADP, and activate myosin II) is found toward the rear of the cell. Based on your…

The proline isomerase activity of FK506 is central to its mechanism of action as an inhibitor of the immune system response. * True * False
Which of the following interactions are due to the complementarity of the molecules: various proteins in the process of self-assembling of cellular organelles; amino acid radicals during the formation of the tertiary structure of the protein. Protein-ligand functionally linked enzymes during the formation of polyenzyme complexes; protein with water dipoles in solution Ligand-receptor
The biomolecular interaction between protein receptors and ligands is similar to that of en- zymes and substrates, which depends in part on the shape of the protein. The shape of a protein, in turn, depends on the presence of appropriate chemical bonds in the protein. Many common medications function by altering the interactions between protein receptors and ligands, thereby interfering with the normal response of a cell to specific signals. Which of the following best describes a mechanism by which a drug might interfere with a normal cellular response? A B A medication causes the cell to become more permeable and unable to maintain the conditions that allow a normal response. с A medication interrupts the electron transport chain in a cell and makes it unable to syn- thesize sufficient ATP. D A medication enters the nucleus of a cell and alters the nucleic sequence for a specific receptor protein. A medication enters a target cell and acts as an inhibitor to an intercellular protein…

Give an example of a reducing sugar and a non-reducing sugar. What is the chemical group responsible for the reduction reaction in a reducing sugar? Certain fats are important components of a healthy diet. But transfats are associated with increased riskof heart disease. Are transfats saturated or unsaturated fatty acids? What is the difference in chemicalstructure between a transfat versus a cisfat? DNA and RNA are information molecules with different roles in gene expression. List three differences between these two types of molecules.
Small molecules are used as inhibitors of protein action - as drugs. They most often do this by blocking the active site within the protein. Potential drugs can be screened computationally to determine if they are strongly bound to the protein. Figure 1 shows a possible conformation of a candidate drug molecule, 4-bromo-2- carboxymethylamide-pyrrole (abbreviation: BCMAP) at the active site of a protein (abbreviation: PR). Figure 2 shows the full protein structure whilst figure 3 shows a known inhibitor of the protein at the site, overlayed with another calculated conformer of BCMAP. (a) Explain what types of interactions, both intermolecular and intramolecular, that a molecular mechanics forcefield must be able to describe in order to be able to accurately determine the geometry of BCMAP in the protein. Identify which interactions will be the most important to describe accurately. Figure 1.4-bromo-2-carboxymethylamide-pyrrole (BCMAP) (C, N, O, and Br atoms in yellow, blue, red, and…
