Carbon dioxide is produced as a byproduct which is a waste that requires to be excreted. Active transport requires cellular energy in the form of ATP (primary), and energy stored (secondary). Eventually the cells begin to die and the active transport pumps shut down the plasma membranes of Joseph’s heart. Question C: Which intracellular organelles have membranes as part of their structure? How would the breakdown of the membranes of these structures affect the function of Joseph’s heart cells?
Why does the pH of the blood decrease in a person who has digested trematol? * A. Physical exertion would increase the production of latic acid by fermentation, and the build up of lactic acid decreases blood pH when liver enzymes are blocked. 4. Dinitrophenol (DNP) is an uncoupler, or has the ability to separate the flow of electrons and the pumping of H+ ions for ATP synthesis.
This will lead to degradation of adenine nucleotides. This, then leads to concomitant hypoglycemia. This can lead to liver damage. The specific substrate acted on by adolase B is F1P (Fructose 1 phosphate). When the aldolase B is not functioning, we cannot process F1P, which causes an accumulation of F1P in the liver.
B) permanent dipoles of molecules containing covalent bonds between atoms of very different electronegativities. C) the hydrophobic effect. D) ion pairing between oppositely charged functional groups. Answer: A Page Ref: Section 5 28) The aggregation of nonpolar molecules or groups in water is thermodynamically due to the A) increased entropy of the nonpolar molecules when they associate. B) decreased enthalpy of the system.
Advanced biology week 1 assignment 1. Bacteria are prokaryotes because they are not living organisms; they are simply genetic information wrapped in a protein sheath and they cannot replicate without the help of a cell. 2. Coccus bacteria is bacteria have a spherical shape. In nature, these bacteria may exist as individuals cells or be grouped together.
Autumn Hamman GE 258 A & P 1 Unit 2 Case study: The Cellular Level of Organization “Joseph’s story” Question B: Assuming Joseph’s heart has stopped, what cellular processes and membrane functions are going to be affected by the loss of oxygen, blood glucose, and waste removal? As the blood slows and the flow of oxygen and glucose slows, each cells continues to work rapidly burning up its ATP supply. Carbon dioxide builds in the cells and the pH balance begins to drop. Eventually the cells begin to die and the Active transport pumps shut down the plasma membranes of Joseph’s heart. The cells become leaky; sodium slowly began to leak into the cells, and potassium leaked out.
Exercise 10: Acid-Base Balance: Activity 3: Renal Responses to Respiratory Acidosis and Respiratory Alkalosis Lab Report Pre-lab Quiz Results You have not completed the Pre-lab Quiz. 07/18/13 page 1 Experiment Results Predict Question: Predict Question 1: What effect do you think lowering the PCO2 will have on [H+ ] and [HCO3- ] in the urine? Your answer : d. [H+ ] will decrease and [HCO3- ] will increase. Predict Question 2: What effect do you think raising the PCO2 will have on [H+ ] and [HCO3- ] in the urine? Your answer : c. [H+ ] will increase and [HCO3- ] will decrease.
It is produced by reacting nitric acid and sulphuric acid simultaneously. The lone pair from oxygen breaks the OH bond when it comes in contact with sulphuric acid. Furthermore, NO2OH2 break and dissociate to form H2O water along with the electrophiles NO2. The electrons from the benzene ring attack NO2 causing the double bond to break. Multiple resonance is created from the movement of electrons.
Cyanide is a poison that very specifically blocks the transport of electrons in the electron transport chain. Based on the purpose of this part of cellular respiration, why would you hypothesize that cyanide is so deadly? (1 mark) Cyanide binds to the cytochrome c oxidase enzyme inhibiting the transfer of electrons from fourth complex to the oxygen molecule; cyanide is so deadly because it prevents the oxidative phosphorylation. The tissues (primarily brain and heart) that produce ATP aerobically can no longer use oxygen for the energy production, therefore, they start producing energy anaerobically which affects the functioning of tissues and after sometime the tissues can no longer produce energy which ultimately leads to
Introduction Nucelophilic substitutions are chemical reactions in which an electron rich nucleophile attacks the electron poor electrophile1. There are two classes of nucelophilic reactions – SN1, and SN2. The SN1 reaction is a 2 step, uni-molecular reaction, which is independent of the nucleophile. It requires a highly substituted electrophile since there is a formation of a carbocation in its rate determining step, good polar protic solvents which stabilize the carbocation and a good leaving group1. On the other hand, a SN2 reaction is a concerted, bimolecular reaction which has one slow, transition state1.
