Summary Introduction
Introduction:
A variety of organs and mechanisms have been evolved in the animals that allow them to cope up with the problems of water balance and excretion of nitrogenous waste. In many animals, removal of salts or water from the body is linked with the

- For each of the following problems calculate the following: (Week 6-3 Video with 6-1 and 6-2) Consult the total catabolic pathways on the last page as a reference for the following questions. A. How much NADH and FADH2 is produced and fed into the electron transport chain (If any)? B. How much ATP is made from oxidative phosphorylation (OP), if any? Feed the NADH and FADH2 into the electron transport chain: 3ATP/NADH, 2ATP/FADH2 C. How much ATP is made by substrate level phosphorylation (SLP)? D. How much total ATP is made? Add the SLP and OP together. 1. Aerobic respiration using 0.5 mole of glucose?

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forwardDon't copy the other answerarrow_forward
