What would be a typical regulatory system in a metabolic pathway? The pathway’s product slows it down, so that the product is maintained at a constant level in the cell or organism. The pathway’s product makes it go faster, so that more and more of the product builds up in the cell or body. Feedback Correct Question 3 Points: 10 out of 10 Which best describes body weight regulation in a normal human who is living in a modern society? Our normal responses of appetite and metabolism tend to cause weight gain in modern societies, and they also tend to make weight loss difficult. Our normal responses of appetite and metabolism ensure that adults remain at a given normal body weight. Any change from this normal weight sets in motion responses that return the body to its normal weight. Feedback Right. Our normal tendencies lead to weight gain in modern societies. At the same time, certain health problems or psychological conditions can lead to dangerous weight loss (anorexia). Maintenance of healthy weight is not automatic.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
