Question :</h2>
Which of the following is not a function of cerebrospinal fluid?
A) acts as a transport medium for waste products
B) provides cushioning for delicate neural tissues
C) provides buoyant support for the brain
D) produces ATP for impulse transmission
E) acts as a transport medium for nutrients
Answer:
D) produces ATP for impulse transmission
Explanation:
CSF doesn't produce ATP for the impulse transmission hence option D is the right option.
Cerebrospinal fluid (CSF) performs following functions :
1) Protects the brain and spinal cord from trauma
2) It supplies nutrients to the nervous tissues
3) It removes the waste products from cerebral metabolism.
A. Cell Membrane, a phospholipid contains a hydrophilic phosphate head and two fatty acid tails
A. Lipid bilayer: the phospholipid bilayer is the membrane of a cell. The bilayer contains lipids, membrane proteins, cholesterol, receptors for various molecules, pumps to transport ions and solutes against the concentration gradient, and many other items necessary for a cell to function and work together with other cells.
b. Osmotic pressure: Osmosis is the flow of water across a semipermeable barrier from an area of low solute concentration to high solute concentration. Osmotic pressure is the lowest possible pressure to prevent this water movement.
c. Endoplasmic Reticulum: the Rough ER synthesizes proteins for use outside the cell. The Smooth ER produces lipids and some steroidal hormones.
A. Lipid Bilayer is therefore the correct answer. Osmotic pressure does not involve the various components of the cell membrane, and the ER's produce proteins and hormones. Therefore A is right.
Hope this helps! :) Let me know if you need a clarification.
Number four the answer is d
number five the answer is b
