The carbohydrate-rich foods you consume start out with a variety of complex and simple carbohydrates, but ultimately, they must be digested into monosaccharides in order to be absorbed into the bloodstream. blood glucose levels are regulated closely by insulin and glucagon (and four other hormones) in order to ensure a steady supply of glucose to the brain and other tissues. select all of the sentences below that correctly describe a step in the processes of digestion, absorption, and/or blood glucose regulation. select all that apply.1-after a meal, blood glucose levels rise, and the pancreas secretes glucagon, which stimulates glycogenolysis.2-after a meal, blood glucose levels rise, and the pancreas secretes insulin, which aids in glucose uptake into cells and stimulates glycogenesis.3-most fiber is broken down by bacteria in the small intestine, and most of the smaller chains are absorbed through the brush border into the bloodstream.4-glucose, fructose, and galactose are absorbed by the cells of the small intestine and then enter the bloodstream.5-the brush border of the small intestine produces enzymes that digest disaccharides into glucose, fructose, and galactose.
