Starch is used to store energy and cellulose is a structural polysaccharide. The key differences that explain these functions are cellulose with high branching aids strong structures, and starch with low branching makes for easy energy release. beta 1-4 and alpha 1-6 glycosidic linkage of starch can create branches, and alpha 1-4 linkages in cellulose creates strength. the unbranched structure of starch makes it easy to process for energy, and the branched structure in cellulose creates strong bonds. alpha 1-4 and alpha 1-6 glycosidic linkage in starch creates branching, and beta 1-4 linkages in cellulose creates unbranched structures.

43. Altering the three-dimensional structure of an enzyme might A) prevent the enzyme from adding energy to a reaction. B) change the type of product that binds the enzyme’s active site. C) prevent the substrate from binding the enzyme’s active site.D) change the amount of energy needed for a reaction. E) change the type of product produced in the reaction.

31. The charge on amino acids in the active site of an enzyme would be affected by A) pH. B) substrate concentration. C) antibiotics. D) temperature.

What feature of genetic mutations can eventually lead to the evolution of new species? Mutations never affect protein structure or function. Mutations produce changes in the DNA sequence of a gene. Mutations always produce harmful effects. Mutations are not a mechanism through which biological evolution occurs. Mutations always produce beneficial effects.

Convert the following numbers from binary to decimal, assuming 6-bit two’s complement binary representation: a) 101011 b) 011101 c) 111111

Using De Morgan’s Laws, NOT the following conditions.  Your answer should contain no spaces.  Here is an example: q < 1 || q == 5 will result in the following if NOTed: q>=1&&q!=5 (a) 9 == x || y 1 && z >= 5     is

Convert the following decimal values into packed Binary Coded Decimal (BCD) encodings.  Your answer should have a space between each 4-bit sequence.  For example, 0101 0001. a) 201 b) 647

Perform the following additions, assuming 7-bit two’s complement binary representation.  Show the effect on the status bits (NZVC).  Example: Example: Note: that this is a 6-bit example and the questions below are for 7-bit.ex) 101000 + 100000 001000 NZVC 0011 Result was 1001000 but the 1 is carry-out (C=1). Negative + Negative should be Negative but positive so overflow (V=1)a) 1101001 + 1110001 NZVC b) 1111111 + 0110101 NZVC
