To determine: The equation that shows the relation between carbon dioxide and pH.
Introduction: Carbon dioxide can be considered as an essential metabolite in almost all the living organisms. It can freely diffuse in and out of the cells of an organism.
To determine: The enzymes that are responsible for an increase in the rate of such a reaction.
Introduction: An enzyme is responsible for increasing the rate of a particular reaction. An enzyme is never used up during the whole reaction.
To determine: The types of cells that have a high concentration of this enzyme.
Introduction: The enzymes are responsible for enhancing the

- Human serum albumin is another protein that has an extremely long half life in the body. Due to this, the low probability event, glycation does take place. Write a rate law for this reaction: Rate = k[glucose] Rate = k[hemoglobin] Rate = k [glucose hemoglobin albumin]arrow_forwardCarbonic anhydrase catalyzes the reaction between carbon dioxide and water to produce carbonic acid. Zn+2 cation assists in the catalytic process. Which function does carbon dioxide play in this process? A) It is an enzyme b) It is a substrate c) it is a cofactor d) it is the active site Carbonic anhydrase catalyzes the reaction between carbon dioxide and water to produce carbonic acid. Zn+2 cation assists in the catalytic process. Which function does Zn+2 cation play in this process? A) It is an enzyme b) It is a substrate c) it is a cofactor d) it is the active site The amino acids Asp, Ser, His and Glu, which are part of the polypeptide chain, bind to both carbon dioxide and Zn+2 cation during the catalytic process. Which role are these amino acids playing in the catalytic process? A) they are prosthetic groups b) they are coenzymes. C) they are reaction products d) They are found in the active site Kinases catalyze the transfer of which group from one…arrow_forwardMatch each component of this figure with the corresponding reduced or oxidized level.arrow_forward
- What are the major transport mechanisms for CO2? Explainarrow_forwardList the four factors that influence the rate of a chemical reaction and state whether increasing the factor will increase or decrease the rate of the reaction.arrow_forwardExergonic reactions such as the breakdown of ATP, are said to be “spontaneous.” However, by themselves, even exergonic reactions often proceed very slowly. What part of the curve helps to explain this? WHICH LETTER REPRESENTS IT? Thank you !(:arrow_forward
- Complete the following tables by providing the reactants/substrates, enzymes and their functions as well as the products in each step of thefatty acid pathways.arrow_forwardThe actions of cardiac glycoside drugs are not confined exclusively to heart tissue. How would ingestion of a cardiac glycoside affect uptake of glucose in the intestine? Refer to actions of the cardiac glycoside on the system in the image above in your answer. 5. Calculate the free energy change associated with moving glucose into the cell. The experimental conditions are as follows: 37 °C, 5 mM extracellular glucose, 0.4 mM intracellular glucose. Show all work.arrow_forwardWhen the chemical dinitrophenol (DNP) is added to mitochondria, the inner membrane becomes permeable to protons. When the drug valinomycin is added to mitochondria, the inner membrane becomes permeable to potassium ions (K+). A. How will the electrochemical proton gradient change in response to DNP? B. How will it change in response to valinomycin?arrow_forward
- Ethylene glycol (HO−CH2−CH2−OH) is a major component of antifreeze. In the body, it is first converted to HOOC−CHO (oxoethanoic acid) and then to HOOC−COOH (oxalic acid), which is toxic. What class of enzyme catalyzes both of the reactions of ethylene glycol? The treatment for the ingestion of ethylene glycol is an intravenous solution of ethanol. How might this help prevent toxic levels of oxalic acid in the body?arrow_forwardPlease handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.arrow_forwardProduce a graph that shows the effect of pH on the rate of reaction for amylase from the tablearrow_forward
