Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.

- how reaction rate of enzyme-catalyzed reactions are affected by substrate and enzyme concentration, temperature, and pHIn any given enzyme, the active site is only a small portionof the entire molecule. Synthesis of such a relatively largemolecular machine requires an enormous amount of cellular energy. Explain why this inefficiency is tolerated.Most reactions, including enzyme-catalyzed reactions, proceed faster at higher temperatures. However, for a given enzyme, the rate drops off abruptly at a certain temperature. Account for this behavior
- The Effect of Various Factors on the Rate of an Enzyme Reaction. These experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H2O2 (hydrogen peroxide), to produce H2O and O2. The O2 is released as bubbles. Therefore, the more bubbles you see, the greater the reaction. Base your responses on the following data table: The effect of temperature on the rate of enzyme reactions Tube Pre-Treatment Temp °C Treatment Temp °C Prediction - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling Observations - no bubbles + some bubbling ++ strong bubbling +++ very strong bubbling C1 100 100 +++ - C2 25 25 ++ +++ C3 0 4 + ++ What do you conclude about the effect of temperature on enzyme activity? Don’t just say that it has an effect, say how it affects it. Based on your conclusion, do you think you might digest ice cream at a slower or faster rate than a hot soup?The Effect of Various Factors on the Rate of an Enzyme Reaction. These experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H2O2 (hydrogen peroxide), to produce H2O and O2. The O2 is released as bubbles. Therefore, the more bubbles you see, the greater the reaction.

Again, thinking of the effect of pH on enzyme activity, why does the pancreas secrete HCO3-? What would you predict to happen to digestion and absorption in the small intestine if the pancreas stopped producing bicarbonate?Triose phosphate isomerase is a diffusion-controlled enzyme. What reaction is catalyzed by this enzyme (structures of molecules not needed)? Explain why this enzyme has evolved to be a very fast enzyme
- The Krebs cycle and why enzymes are not needed to power it and how enzymes can be affected by temperature, specfically, amylase in human salivahow allosteric regulation is fundamentally different from competitive/uncompetitive/mixed inhibition and why Michaelis-Menten and Lineweaver-Burk analysis cannot be used for allosteric enzymes.Most enzymes do not operate at their biochemical optima inside cells. Suggest why this is the case.
- The rate of a chemical reaction will double (reaction will go twice as fast) for every 10°C increase in temperature. This observation holds for enzyme-catalyzed reactions up to a certain temperature range (different for each enzyme), at which the rate stops increasing and then decreases sharply as the temperature increases. Explain.a biochemical pathway in which c02 is converted onto organic compoundsHow ATP drives chemical work: Energy coupling using ATP hydrolysis.In this example, the exergonic process of ATP hydrolysis is used to drive an endergonic process—thecellular synthesis of the amino acid glutamine from glutamic acid and ammonia.
