Physio Coaching Flashcards
- The fluids outside and inside the cell is important to maintain the homeostasis. Which of the following is true about extracellular fluids and intracellular fluids?
a. The intracellular fluids contain large amount of potassium, magnesium, chloride ions. The extracellular contain sodium, bicarbonate ions and phosphate ions
b. The intracellular fluids contain large amount of potassium, magnesium, sodium.
The extracellular contain sodium, bicarbonate ions and phosphate ions
c. The intracellular fluids contain large amount of potassium, magnesium, phosphate ions. The extracellular contain sodium, bicarbonate ions and chloride ions
d. NOTA
- Which of the following describes the positive feedback?
a. Most common feedback in the body
b. this type of feedback triggers when some factors of the body is deficient or excessive c. Vicious cycle
d. changes that return the factor toward certain mean value
- Specialization of a plasma membrane
a. Tight junction
b. gap junction
C. Tight and Gap Junction
d. NMU
- All of the following describe the organelles, Except:
a. Little organs in the cytoplasm
b. subcellular structures specialized for specific functions such as manufacturing proteins or producing ATP
c. Organelles can be thought of as individual workstations within the cell, each
responsible for performing specific tasks
d. NOTA
- Which of the ff describes the diffusion?
I. Diffusion through the cell membrane is divided into two subtypes, called simple diffusion and facilitated diffusion
II. Simple Diffusion means that kinetic movement of molecules or ions through a membrane opening or through intermolecular spaces without any interaction with carrier proteins in the membrane
III. Facilitated diffusion requires interaction of a carrier protein.
IV. The carrier protein in facilitated diffusion aids passage of the molecules or ions through the membrane by binding chemically with them.
a. I, II, III
b. I, II, III
c. I, II, III, IV
d. Only I
