Concept explainers
Interpretation: It should be identified the reduced form of nicotinamide adenine dinucleotide.
Concept Introduction:
Proteins: Proteins are
Lipids: Lipids are the important type of compound found in organism.
They are the principle of components of the cell membrane and a repository of chemical energy in the form of fat.
In addition to the some of the chemical messenger called hormones are lipids.
Polar compound tends to be soluble in polar solvent such as water. But nonpolar compound are soluble in non-polar solvent but they tends not to be soluble in organic solvent.
Fluid – mosaic model:
A cell membrane is made up primarily of a phospholipid bilayer in which are embedded cholesterol, other lipids and proteins . Movements whining a layer occurs, but movement from one side of the bilayer to the other is rare.

Chemistry & Chemical Reactivity
- Malate is converted to oxaloacetate by the enzyme malate dehydrogenase in the final reaction of the citrate cycle. This redox reaction results in the reduction of NAD+ to generate NADH + H+. Answer the three questions below and choose the correct answer. (a) Calculate the delta AE for the malate dehydrogenase reaction. (b) Calculate AG and determine if the conversion from malate to oxaloacetate is favorable under standard biochemical conditions using the information below. (c) Under cellular conditions is the AG favorable or unfavorable? Oxaloacetate + 2H* + 2e- --> Malate E° = -0.17 V NAD* + H+ + 2e- --> NADH E°' = -0.32 Varrow_forwardGlycerol kinase catalyzes the phosphorylation of glycerol from ATP, yielding glycerol-3-phosphate and ADP. The standard state free energy for hydrolysis of glycerol-3- phosphate is -9.20 kj/mol and for the hydrolysis of ATP is-30.5 kJ/mol.

What is the most likely explanation for the loss of activity? (A) Urea binds to the active site of the enzyme competitively with the substrate. (B) Urea causes the cleavage of the peptide bonds in the enzyme. (C) Urea causes the enzyme to denature and lose its specific three-dimensional shape. (D) Urea reacts with disulfide bonds in the enzyme.arrow_forward

- When the reaction below reaches equilibrium, does the equilibrium lie on the left or the right side? Briefly explain. ClO– + CH3CO2H ⇌ HClO + CH3CO2– When the terminal phosphate is cleaved from the adenosine triphosphate molecule, the products are adenosine diphosphate and inorganic phosphate, ATP + H2O ––> ADP + Pi, where Pi stands for the various forms of phosphate that exist at the pH of the particular solution. If the total concentration of Pi is 2.5 x 10–2M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4? Permanganate, MnO4–, can act as an oxidizing agent in both acidic and basic aqueous solutions. Balance each of the following reactions by the half–reaction method, showing all steps in the balancing process.
