Question

Starch and glycogen are both polymers of fructose. glucose1-phosphate. sucrose. alpha-D-glucose. beta-D glucose. The bacterium E. coli requires simple organic molecules for growth and energy-it therefore a: photoautotroph chemoautotroph lithotroph chemoheterotroph photoheterotroph. The major reason that antiparallel beta-stranded protein structures are more stable parallel beta-stranded structures is that the latter: are in a slightly less extended configuration than antiparallel strands. have weaker hydrogen bonds laterally between adjacent strands. do not have as many disulfide crosslinks between adjacent strands. do not stack in sheets as well as antiparallel strands. have fewer lateral hydrogen bonds than antiparallel strands.

Explanation / Answer

1. Answer is option D. They both are polysaccharides. Both starch and glycogen are similar in its monomeric unit which is glucose.

2. Answer is option C. Chemoheterotrophs are defined as those organisms that obtain their energy by the oxidation of electron donor in their environment.

3. Answer is option B. Beta-sheets consists of the beta strands which are connected laterally by the hydrogen bond. So, the intensity of hydrogen bonds will determine which struture will be stronger.
