Which of the following is not involved in glycogen synthesis? glycogeninamylo-(1,4 to 1,6)-transglycosylaseglycogen phosphorylaseudp-glucoseglycogen synthase

The correct answer is: Glycogen phosphorylase UDP-glucose

Steps of glycogen synthesis (glycogenesis) are:

•Glucose conversion into glucose 6-phosphate by the glucokinase enzyme

•Glucose-6-phosphate conversion into glucose-1-phosphate by the phosphoglucomutase enzyme

•Glucose-1-phosphate conversion into UDP-glucose by the enzyme UDP-glucose pyrophosphorylase

•Creation of initial short glycogen chains by glycogenin

•UDP-glucose is added to the growing glycogen chain to the 4-hydroxyl group of the glucosyl residue by the glycogen synthase enzyme

•Branches are made by glycogen branching enzyme (amylo-α(1:4)→α(1:6)transglycosylase).

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
