- Which of the following is an appropriate Federal Reserve action to stimulate the United States economy?(A) Selling government bonds on the open market(B) Increasing the discount rate(C) Reducing the reserve requirement(D) Cutting taxes
- In marketing research, a firm might consider using secondary data over primary data because(A) secondary data usually cost less(B) secondary data are usually more accurate(C) primary data are usually non specific(D) primary data are likely to be outdated
- Network of hydrogen bonds gives cellulose:- MECHANICAL STRENGTH: it is a major component of plant cell walls and makes the plant (leaves, branches, stem) strong- CHEMICAL STABILITY
- glycogen is an organic molecule (more specifically carbohydrate, more specifically starch), the majority of which are non-polar. therefore glycogen cannot interact with the dipole on water molecules. this is important as subsequently glycogen does not affect the water potential of cells
- a branched molecule with a large surface area for rapid hydrolysis by enzymes during respiration so used for energy storage so that glucose can be accessed quickly
- long molecules made of a non-polar hydrocarbon chain with a polar carboxyl acid group at one end
- a coiled linear molecule of alpha glucose joined by 1-4 and 1-6 glycosidic bonds (hydrogen bonds are present)
- used for energy storage and food reserve as its branched structure provides a large surface area for enzymes to carry out hydrolysis
- lipids with a hydrocarbon chain consisting of C-C and one C=C bond
- a non-polar hydrophobic molecule, composed of a glycerol base and 3 fatty acids
- the linear sequence of amino acids joined by peptide bonds in a polypeptide chainBONDS PRESENT: PEPTIDE BONDS
- polypeptide chain is wound to form a helix, held together by hydrogen bonds running parallel with the long helical axis. it is very stable and strong
- used for energy storage as its linear structure creates a compact molecule that can store a lot of energy in a small space (plants)
- the most basic level of protein folding, held together by hydrogen bonds between the carboxyl and the amino groups in the polypeptide backboneBONDS PRESENT: PEPTIDE BONDS, HYDROGEN BONDS
- the polypeptide chains zigzags back and forward forming a sheet of antiparallel strands, held together by hydrogen bonds
- when 2 or more polypeptide chains join to form a protein; 4 folded subunits fold to form a large aggregate protein complex
- an atom with an unequal number of electrons and protons
- linear molecule connected by hydrogen bonds provide strength and structural support in plants
