Lab partners, Mary and Jose, have drawn the diagram above to represent what they observed in their lab experiment. They think the sugar molecules have moved across the plasma membrane but they disagree as to why this has happened. Which statement below best argues the correct reason for the molecule movement? (DOK.2, AKS 2A) Question 22 options: The sugar molecules moved across the membrane through diffusion due to the higher concentration of molecules inside the cell and lesser concentration of molecules outside of the cell. The movement of molecules by diffusion doesn’t require energy. The sugar molecules moved across the membrane through active transport due to the higher concentration of molecules on outside of the cell and lesser concentration of molecules inside the cell. The movement of molecules by active transport requires energy The sugar molecules moved across the membrane through osmosis due to the higher concentration of water molecules outside the cell and the lesser concentration of water molecules inside the cell. The movement of molecules by osmosis requires energy. The sugar molecules moved across the membrane through facilitated diffusion due to the higher concentration of molecules outside of the cell and the lesser concentration of molecules inside the cell. The movement of molecules by facilitated diffusion doesn’t require energy, but happens via carrier proteins

Glucose is a form of sugar found in the blood cells use glucose as a source of energy, but too much or too little can cause serious health issues so, the body uses the hormone insulin to regulate glucose n the blood insulin maintain glucose levels in the blood if blood glucose lovels got very high, what would you expect to see happen to insulin levels?
