The glucose transport will decrease in low temperatures as it is an enzyme mediated mechanism and the activity of the enzymes decreases at low temperatures.
Decreased temperatures have negative impact on cell membrane and transport. When the temperature is low, the tails of phospholipids become rigid and movement is slow. The overall fluidity of the membrane is decreased and this restricts the entry of glucose into the cell. The glucose transport occurs via facilitated diffusion and diffusion is also a temperature dependent process.
Nondisjunction happens when the chromosomes don't separate correctly during meiosis, which can result in an extra copy of certain chromosome. I hope this helped a little bit.
