Bi Sci 001 Friday March 5, 1999 Announcements: Have a good Spring Break. Lecture notes: What happens to the Carbohydrates we eat? Complex carbohydrates are broken down and the glucose is released slowly into the blood stream. Simple carbohydrates are absorbed rapidly into the blood stream, no digestion needed. The presence of glucose in the blood stream causes the release of insulin from the endocrine cells in the pancreas. Insulin causes increased uptake of glucose by cells. What is the Fate of glucose in cells? Liver : glucose is made into glycogen, or amino acids, or fats, or energy. Fat cells : glucose is used for fat production or energy. Muscle cells : glucose is made into energy or glycogen. Others : glucose is made into energy. This restores the normal blood glucose level. What happens to the Fat we eat? Digested fats become 3 fatty acids and glycerol . The transport of fats and cholesterol in the blood is complicated and involves phospholipid/protein carriers. (chylomicron, HDL, LDL, VLDL) Fatty acids are taken up by adipose cells, liver and muscle mainly.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
