MD 103: HISTOLOGY Quiz 1: INTRODUCTION TO THE CELL CMED 1A | Dr. Erwin Jandoc QUESTIONS ANSWERS RATIONALE REFERENCE What are the three Catalase Enzymes such as superoxide Alberts B, reactive enzymes Superoxide dismutase (SOD), catalase, and Johnson A, Lewis that are present in dismutase glutathione peroxidase are cellular J, et al. Molecular peroxisomes? Glutathione defenses against ROS found in Biology of the peroxidase peroxisomes. Cell. 4th edition. New York: Garland Science; 2002. Peroxisomes. It is a type of Euchromatin Chromatin with DNA that is active in Junqueira's Basic chromatin that is transcription stains lightly and is called Histology Text transcriptionally euchromatin. The dispersed and Atlas 13th active and less euchromatin contains regions of the edition p. 174 dense. DNA undergoing active transcription and is more prominent in metabolically active cells. It is a type of Heterochromatin Heterochromatin is always more Ref: Junqueira's chromatin that is compact than euchromatin, shows little Basic Histology condensed but or no transcriptional activity. Text and Atlas inactive. 15th edition p. 54 It is a type of drug Colchicine Colchicine is known to stabilise McLoughlin, E. that destabilizes microtubule structures at low C., & O'Boyle, N. microtubules and concentrations and destabilise them at M.

Pharmaceuticals (Basel, Switzerland), 13(1), 8. Part of plasma Cholesterol The plasma membrane (cell Junqueira's Basic membrane membrane or plasmalemma) is the Histology Text responsible for lipid bilayer with embedded proteins and Atlas 15th synthesis of steroid that surrounds a cell and is seen only edition p. 51; hormones: with the TEM. The lipid bilayer forms Paul E. Marik, in from amphipathic phospholipids, Critical Care stabilized by cholesterol, and contains Nephrology many embedded (integral) proteins (Third Edition), and many peripheral proteins on its 2019 cytoplasmic surface. Cholesterol is the principal precursor for steroid biosynthesis in steroidogenic tissue.  QUESTIONS ANSWERS RATIONALE REFERENCE An organelle uses to Ribosomes The ribosome is universally Vanzi, F., interpret for DNA to responsible for synthesizing proteins Vladimirov, S., RNA to mRNA: by translating the genetic code Knudsen, C.
