27. Body fluid compartments include all of the following Except

3. How many mEq of Cl- are in a solution containing 60 mM Glucose, 10 mM Fructose, 200 mM MgCl2 and 400 mM KCl?

17. After a protein is synthesized by the ribosomes, it is sent to the golgi apparatus for what event?

33. Cells that synthesize and secrete a lot of digestive enzymes contain many

32. Microvilli

26. In humans, glucose is stored as

30. Ion channels are

34. Which is a type of post-translational modification?

37. Properties of Ion channels:

If blood temperature rises too high, this is sensed by specialized neurons in the hypothalamus of the brain. They signal the brain stem, which in turn sends signals to the blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. At the same time the brain stem also activates sweat glands and sweating.

10. What level of regulation is described?

16. In each cycle of the Na+/K+ ATPase (Na+/K+ pump)

12. An organelle that contains digestive enzymes is called a/the

19. Transcription takes place in the cell ______. Translation takes place in the cell ______.

If blood temperature rises too high, this is sensed by specialized neurons in the hypothalamus of the brain. They signal the brain stem, which in turn sends signals to the blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. At the same time the brain stem also activates sweat glands and sweating.
7. What is the controlled variable in the preceding example?

5. Replication occurs in the _____. Post-translational modification occurs in the _____.

28. Chemical reactions in cells are powered by

22. Which of the 11 human organ systems is vital in regulating human physiology by conserving heat and protecting us from the external environment?

4. What is osmolarity of that same solution, containing 60 mM Glucose, 10 mM Fructose, 200 mM MgCl2 and 400 mM KCl?

If blood temperature rises too high, this is sensed by specialized neurons in the hypothalamus of the brain. They signal the brain stem, which in turn sends signals to the blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. At the same time the brain stem also activates sweat glands and sweating.
