How the cells are able to synthesize different molecules, in terms of cytoplasmic determinants and gene regulation. Concept introduction : During embryonic development, the zygote is differentiated to form mature cells with a specific structure and function. The process is known as cell differentiation . As the embryo enlarges and the cell number increases, the cells communicate with each other in the embryo. Certain cytoplasmic determinants and signals from other nearby embryonic cells regulate the specific gene expression. Signal molecules regulate gene expression by the activation and deactivation of specific genes of other cells in a process known as induction . These processes together determine the fate of embryonic cells.

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? NADH FADH2 OP ATP SLP ATP Total ATP Show your work using dimensional analysis here:

Aerobic respiration of one lipid molecule. 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…
