A) steroid molecule B) phospholipid molecule C) fatty acid molecule D) pentose molecule E) oligosaccharide molecule 8) In the fractionation of homogenized cells using centrifugation, the primary factor that determines 8) whether a specific cellular component ends up in the supernatant or the pellet is A) the presence or absence of nucleic acids in the component. B) the presence or absence of lipids in the component. C) the relative solubility of the component. D) the size and weight of the component. E) the percentage of carbohydrates in the component 9) If radioactive deoxythymidine triphosphate (dITP) is added to a culture of rapidly growing 9 bacterial cells, where in the cell would you expect to find the greatest concentration of radioactivity? A) nucleus B) nucleoid C) endoplasmic reticulurm D) ribosomes E) cytoplasm 10) Which of the following contains hydrolytic enzymes? 10) A) vacuole B) mitochondrion C) peroxisome D) Golgi apparatus E) lysosomeExplanation / Answer
6) The correct optionC.is the reaction of a fat, forming glycerol and fatty acids with the consumption of water.
Hydrolysis is a process in which the chemical breakdown of a compound due to reaction with water.
7) The correct option is A. steroid molecule.
The steroid molecule structure is composed of seventeen carbon atoms,which is bonded in four fused rings: three six-member cyclohexane rings and one five-member cyclopentane ring.
8) The correct option is D.the size and weight of the component.
In the fractionation of homogenized cells using centrifugation, the primary factor that determines whether a specific cellular component ends up in the supernatant or the pellet is the size and weight of the component.
9) The correct option is B.nucleoid.
If radioactive deoxythymidine triphosphate is added to a culture of rapidly growing bacterial cells, nucleoid has the greatest concentration of radioactivity.
10) The correct option is E.lysosome.
lysosome IS an organelle in the cytoplasm of eukaryotic cells which contains degradative enzymes enclosed in a membrane.
