Restricts movement of materials in and out of the cell B. Is often a triple layer comprised of lipids C. Prevents essential nutrients from escaping D. Contains hydrophobic tails pointing outward - ANSWERSA;C Complete the following DNA strand, and indicate how many bonds are formed for each complementary pair: 3' GGTCATCG 5' 5' CC _____AGC 3' - ANSWERS3' GGTCATCG 5' 5' CCAGTAGC 3' There are 2 bonds formed between A and T, and 3 bonds between G and C. True of False: The genetic material within a prokaryotic cell is contained within a membrane-enclosed region. - ANSWERSFalse How many carbon atoms are present in the monosaccharide glucose? - ANSWERS6 Describe the 4 basic bacterial morphologies. - ANSWERSCoccus (round/spherical), bacillus (rod), vibrio (curved rod) or spirillum (spiral/corkscrew). True or False: Archaea, a eukaryotic class of microorganisms, is capable of surviving harsh environments. - ANSWERSFalse Which of the following microorganisms are considered to be Eukarya? Select all that apply. Animalia Plantae Fungi Protista - ANSWERSAll of them Microorganisms classified as _________ obtain most of their energy by converting light energy into chemical energy. - ANSWERSPlantae A defining characteristic of fungi is the presence of chitin in the cell walls. Which of following also contain chitin? Select all that apply. A. Mushrooms B. Bacteria C. Yeast D. Molds - ANSWERSA, C, D True or False: Protista retain a unicellular classification, as they are unable to form tissue layers. - ANSWERSTrue True of False. All multicellular microorganisms classified as Animalia are heterotrophic - ANSWERSTrue The function of the lysosome is (select all that apply): A. Lipid synthesis B. Protein synthesis C. To produce energy (ATP) D. Protein modification and distribution E. Waste disposal via hydrolytic enzymes - ANSWERSE The function of the mitochondria is (select all that apply): A. Lipid synthesis B. Protein synthesis C. To produce energy (ATP) D. Protein modification and distribution E. Waste disposal via hydrolytic enzymes - ANSWERSC The combination of the cell membrane and the outer membrane is referred to as the (select all that apply): A. Cell wall B. Capsid C. Cell envelope D. Outer leaflet - ANSWERSC What is the smallest biological unit of life? - ANSWERSCell Define an essential amino acid. - ANSWERSAn essential amino acid cannot be produced by the human body and as such must be take in from the environment through alternative sources (i.e) food. Where can the two major types of nucleic acids be found in the cell and what are their roles? - ANSWERSWhile both DNA and RNA can be found in the nucleus (center of the cell), only RNA is capable of leaving the nucleus. DNA contains a vast amount of hereditary information and is responsible for the inheritable characteristics of living organisms. RNA is responsible for deciphering the hereditary information in DNA and using it to synthesize proteins. True or False: Archaea is noted for its ability to survive under harsh conditions. - ANSWERSTrue Microorganisms classified as Plantae obtain most of their energy by converting _____ energy into _______ energy. - ANSWERSLight (sunlight); chemical (sugars) True or False: A defining characteristic of Protista is the inability of colonies to form tissue layers. - ANSWERSTrue Cell walls are found in which of the following (select all that apply): A. Plants B. Fungi C. Bacteria D. Mammalian cells E. Algae - ANSWERSA, B, C, E The function of the ribosome is (select all that apply): A. Lipid synthesis B. Protein synthesis C. To produce energy (ATP) D. Protein modification and distribution E. Waste disposal via hydrolytic enzymes - ANSWERSB
