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 ...
Eleven specific questions related to cell biology, animal vs. plant, photosynthesis, homeostasis, cellular respiration are addressed here
1. A type of cell called a lymphocyte makes proteins that are exported from the cell. You can track the path of these proteins within the cell from production through export by labeling them with radioactive isotopes. Identify which of the following structures would be radioactively labeled in your experiment, listing them in the order in which they would be labeled: chloroplasts, Golgi apparatus, plasma membrane, smooth ER, rough ER, nucleus, mitochondria.
2. Imagine that you are a pediatrician and one of your patients is a newborn who may have a lysosomal storage disease. You remove some cells from the patient and examine them under the microscope. What would you expect to see? Design a series of tests that could reveal whether the patient is indeed suffering from a lysosomal storage disease.
3. What is the primary difference between passive and active transport in terms of concentration gradients?View Full Posting Details
