Question
39) Choose the CORRECT statement about solute concentrations or particles inside and outside the cell. A) In a hypertonic solution, there are more particles inside the cell. B) In a hypotonic solution, there are more particles outside the cell. C) In an isotonic solution the amount of water inside and outside the cell is equal. D) In a hypertonic solution, there is more water outside the cell. E) In a hypotonic solution, there is more water inside the cell. 40) Brad placed a drop of blood in some distilled water. What happened in the red blood cells? A) The cells shrunk. B) The cells burst. C)The cells did not change D) The cells divided into 2 identical cells. E) The cellular metabolism increased in rate. 41) The assisted transport of a molecule across the cell membrane without an expenditure of energy is known as what? A) diffusion B) facilitated transport active transport D) osmosis E) crenation 42) If a cell lacked ribosomes, it would not be able to A) form a spindle apparatus. B) synthesize proteins C) respire oxidatively D) break down fats. E) produce ATP 43) What do the SER and RER have in common? A) the presence of ribosomes B) the formation of transport vesicles C) the synthesis of phospholipids D) the synthesis of proteins E) the processing and modification of proteins 4) Which of the following would be a way of finishing this hypothesis about the function of the Golgi apparatus? If the Golgi apparatus is involved in packaging products for secretion, then A) vesicles must travel from the Golgi to the cell surface. B) vesicles must travel from the RER and SER to the Golgi apparatus. C) the Golgi apparatus must be part of the endomembrane system. D) the Golgi apparatus must consist of 3 to 20 slightly curved sacs. E) the Golgi apparatus would contain proteinsExplanation / Answer
39. Option C is the correct answer. In an isotonic solution, the concentration is same outside ans inside the cell. In hypertonic solution the concentratin outside the cell is higher while in hypotonic solution the concentraion outiside the cell is lower. Thus, the correct answer is option C.
40. Option B is correct. Here water will move inside the cell due to osmosis which result in cell burst.
41. Option A is correct. Diffusion occurs due to concentration gradient and it occurs from higher concentration to lower concentration and thus it does not require energy.
42. Option B is correct. Ribosomes act as plateform for the protein synthesis and thus, protein synthesis will not occur in absence of ribosomes.
43. Option B is the correct answer. The formation of transport vesicles occurs at both smooth and rough endoplasmic reticulum.
44. Option A is correct. Vesicles must travel from the golgi to cell surface in order to secretion occurs. If vesicles will not move to the cell surface, it will not secret out of the cell.
