D) Silicon Contents is correct
Answer:
The ath operon is most likely controlled by the CAP and a repressor similar to the lac operon.
Explanation:
The CAP senses the low concentration of glucose and activates the transcription of the ath operon for it to metabolize the athelose and obtain energy. When the glucose is in high concentrations, the ath repressor, which works as a lac repressor, inhibits the transcription of the ath operon, it does this by binding to a part of the operon called operator getting in the ARN polymerase way and stoping the transcription. If there is glucose, the repressor binds to it and it is not bound to the operon allowing the transcription and metabolism of glucose.
1. Made a lot of products cheaper and accessible
2. Many people moved from their (small farms and rural areas) into cities and earned a living as workers in factories
3. Women started to work in factories, instead of staying at home
Answer:
similarity
Starch, cellulose,dextran and glycogen are all polymers of glucose
differences
monomer/glucose glycosidic bond branching
1.starch α glucose 1-4 and 1-6 branch and unbranced
amylose 1-4 unbranched
amylopectin 1-4 and 1-6 branched
2. dextran α glucose 1-6 branched
3. cellulose β glucose 1-4 unbranched, linear
4. glycogen α glucose 1-4 and 1-6 branched (shorter
branches than starch)
Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.
Explanation:
Starch: Consists of both branched amylopectin and unbranched amylose
Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.
