The most proficient process of generating ATP for most organisms is the aerobic respiration. What molecule is needed for aerobic respiration?
If succinate is employed as the electron donor in oxidative phosphorylation, then how many ATPs must be generated for each pair of electrons donated by the succinate?
Compare and contrast the electron transport systems (ETS) used in the aerobic respiration and the light reactions of photosynthesis. Comprise a description of the inputs and outputs of each ETS and
Aliens land. You find out that in almost all ways, their metabolism is similar to that of humans. One significant difference is that they don't use NAD/NADH. At each and every step in the oxidation
Cell respiration has three portions: Glycolysis, the Krebs cycle, and the electron transport chain. Where in the cell is each found, the molecule(s) which enter each, the molecules at the end of eac
Explain how are carbohydrates significant in RNA and DNA? Explain how do they function as part of DNA and RNA? What's their significance in the construction of the body organs and nerve cells?
In what manners are carbohydrates, lipids, proteins and fibers similar in relation to health, morbidity and mortality? In what manners are they dissimilar?
Compute the isoelectric point (pI) of each of the given amino acids: a) Glycine b) Glutamic acid c) Arginine
Compute the iso-electric point of a protein. I understand that you want to substitute variations of pH until you find out a pI which is close to zero.
An mRNA can be translated by numerous ribosomes at the same time, making a complex called a polysome. How might this capacity be a benefit to the cell?
If a double-stranded DNA molecule was 32 percent cytosine, what would be the percentage of guanine, adenine and thymine? Name the types of RNA delivers amino acids to the site of protein synthesis?
At what substrate concentration will an enzyme characterized by the kcat of 30 s-1 and Km of 0.005 M show one quarter of its maximal rate?
The enzyme carbonic anhydrase is found in the erythrocytes, and consists of a molecular mass of around 30000 Da. The hydration reaction catalyzed by this enzyme is reversible, and plays a vital role
You have just completed a meal comprising of a steak, baked potato and a vegetable. What enzymes would be discharged to digest this meal? From where would each of these be discharged? Explain why is
Food preservation processes interfere with the enzyme action of microbes and prevent them from surviving. How do canning, freezing, pickling and salting interfere with the enzyme activity? Ideas are
SOD is a diffusion-limited enzyme. What does it signify by "diffusion-limited enzyme"?
Write down the two main mechanisms for making sure an adequate amount of neurotransmitter in the synaptic cleft? Comprise three enzymes in the first mechanism.
Write down the basic units of enzymes and explain how are these units arranged and under what conditions do enzymes work best?
Explain the energetic of catalysis in simplest terms? How do enzymes influence forward and reverse reaction rate and what does this signifies?
Compare and contrast the competitive and noncompetitive in terms of: A) How Km is affected in the presence of inhibitor. B) How Vmax is affected in presence of inhibitor.
A new enzyme you are studying has a Km of 7.0mM and a kcat of 126 per second. Determine the initial rate of reaction in units mM/min when 9.3 nanometer enzyme is reacted with the 2.7 mM substrate.
Find out which of the given explains the type of the reaction(s) catalyzed: condensation (carbon-carbon bond formation); dehydration (loss of water); hydration (addition of water); decarboxylation (
An enzyme and its substrate are joined in a test tube however no product is formed. The other molecule is added to the tube, and now the product is formed at the normal rate. Give two reasons.
An enzyme catalyzes a reaction at a velocity of 20 umol/min when the concentration of substrate (S) is 0.01 M. The Km for this substrate is 1 x 10-5 M. supposing that Michaelis-Menten kinetics is fo
Define the words anabolic steroid, synthetic steroid and human growth hormone. Describe how they are similar and how they are dissimilar.
