Which of the following BEST explains the molecular nature of all organic compounds?Organic compounds such as water, monosaccharides, amino acids, and nucleotides compose the basicAmonomers needed to sustain the normal metabolic machinery in cells.Generally speaking, organic compounds are the outcome of chemically bonding hydrogen and carbon atoms,(B)Вand possibly others such as oxygen and nitrogen.Only members of Domain Eukarya (eukaryotic organisms) may reveal organic compounds in their cellular andmolecular structures.Obviously, organic compounds only exists in the living world whereas, inorganic compounds can only be found inDnon-living things

Biomolecules are the biological molecules that are present inside the living organisms. These…

Biological membranes are critical components of cells that allow compartmentalisation of cellular contents. The diagram shows a biological membrane comprised of a lipid bilayer with a single polypeptide integrated into the membrane and spanning the membrane seven times. What types of amino acids are likely present in the parts of the polypeptide chain labelled 1-7 and in the parts of labelled A-G? What is the name of the effect that forces the polypeptide to arrange itself like this within the lipid bilayer? Give an example of a type of molecule that can move freely across the lipid bilayer and explain why it can do so based on its chemical properties.

The naturally-occurring amino acid L-serine (NH2-CH(COOH)-CH2-OH, dry form) shares all of the following features with the naturally-occurring amino acid D-serine, except: the same three-dimensional arrangement of covalent bonds the same stoichiometry the same number of covalent bonds the exact same atoms the same number of atoms
1- (True or False) Adjacent nucleotides are joined by covalent bonds that form between the –OH group on the 3` carbon of one nucleotide and the phosphate on the 5` carbon on the next. 2- (True or False) if a solute is in an aqueous solution, then by definition an hydration shell has formed around it. 3- (True or False) When exposed to water, phospholipids will self-organize into lipid bilayers, and spheres.
The figure below illustrates partial models of a starch molecule and a cellulose molecule, two carbohydrate polymers that are each made of covalently bonded glucose molecules. Starch A B CH₂OH C OH D OH CH₂OH OH OH 0 CH₂OH OH Partial models of a starch and a cellulose molecule Cellulose OH OH OH CH₂OH 0 CH₂OH OH Which of the following best explains why human enzymes that can digest starch cannot also digest cellulose despite the fact that they are both polymers of glucose? OH CH₂OH OH OH Human enzymes can only facilitate the digestion of starch because starch is formed via a dehydration synthesis reaction. The breakdown of starch involves a catabolic reaction, but the breakdown of cellulose Involves an anabolic reaction, which does require enzymatic catalysis. The polymers are digested differently because starch is primarily used for energy stor age while cellulose is primarily used as the component of plant cell walls. The biomolecular differences between the polymers prevent…
