Each enzyme has an optimum pH at which it attains is maximum activity. That optimum pH varies for each enzyme. The optimum range for pepsin is 1.5 – 2; for pancreatic lipase it is 4.0 – 5.0. Any change below or above the optimum pH range for a specific enzyme results in a decrease in enzyme action. Which graph best represents the general statement describing […]

What everyday examples of homeostasis mechanisms can you find?How many other cool things are out there that exhibit a dynamic state of constancy? Be creative, be inquisitive, be curious.Clearly identify the components of a negative feedback system for a specific variable (like temperature, volume, speed, blood pH, etc.) and how each of these five components works:Identify the receptors.What functions as the integrating center?What is the […]

What is your favorite organism?Hi all! Since we are studying how to name and classify organisms this week, I thought it would be fun to share our favorites. Please reply to this discussion with one of your favorite species (could be an animal, fungus, protist, bacterium, plant, etc.). Include the scientific name (genus and species), a picture, and one interesting fact.
