Regarding aerobic respiration, what molecules need transport assistance? What mechanism of transport is used and what type of graph would they have if you plotted speed of transport versus concentration of transported molecule?
Homework Answers
The molecules which required energy for their movement from low concentration to high concentration against concentration gradient required assistance.
Active transport mechanism is used for such transport. One such example is Sodium potassium pump which moves 3 sodium ions out of the cell and 2 potassium ions inside the cell using energy of ATP.
Active transport accumulates high concentration of ions, glucose and amino acids which a cell needs.
If you plot a graph of speed of transport vs concentration of transported molecule, it will be hyperbolic. At low substrate concentration, speed will increase in linear fashion to substrate concentration. But at high substrate concentration, speed will not increase with increase in substrate concentration due to saturation leading to steady state.

Q1: What are catabolism and anabolism (4 marks)? Q2: Under aerobic respiration, a molecule glucose is oxidized to generate 36 ATPs in eukaryote cell while 38 ATPs in prokaryote cell. Explain how this difference occurred (6 marks). Q3: Why aerobic respiration could produce more energy (ATP molecules) than anaerobic respiration and fermentation? By using glucose as the substrate, illustrate how ATP molecules are being produced in each case (15 marks). Q4: "Most microbes use carbohydrate (glucose) as the energy sources...

1) You are in charge of a remediation strategy that requires aerobic, microbial respiration to degrade the compound ethanol in groundwater. There is 840mg/L ethanol in the groundwater; how much oxygen (total, steady state concentration in mg/L) will you need to completely oxidize the ethanol to CO2? Can you accomplish this using only atmospheric oxygen (21 % v/v) at 1 atm total pressure (Pro) and 25°C? If you cannot, what options do you have for increasing oxygen content...

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
