Hello,
I am glad to help you with these problems. I am going to try to do so, however, so that you learn the material and I am not just giving you the answers. I am going to do so by suggesting websites you can visit to learn about the subject and then help to make suggestions for your answer.

QUESTION 1: see the attached diagram, and read below:
Glycolysis, Kreb's cycle and Electron Transport Chain are all part of the three-stage process that breaks down sugars in our cells, a process called "Cellular Respiration". Sugar, in the form of glucose, enters the cell to the CYTOPLASM where it is broken down by the process of GLYCOLYSIS. The products of glycolysis enter the MITOCHONDRIA where the KREB's CYCLE takes place. The ELECTRON TRANSPORT CHAIN follows in the INNER MEMBRANE of the MITROCHONDRIA.

QUESTION 2: please read the "control mechanisms" section of this wikipedia site: http://en.wikipedia.org/wiki/Homeostasis#Control_mechanisms
Try to use common sense here. Your body wants to stay at a relatively stable temperature at all times, right? So how is your body going to react if temperature drops dangerous. First, there must be a mechanism that senses the low temperature (this is called the RECEPTOR). That information then must be passed along to some central information center in our brain that ...
