front 1 What are biomolecules? | back 1 Macromolecules found in living systems containing five or more carbon atoms linked together to form a chain. |
front 2 What are the 4 key biomolecules organisms are composed of? | back 2 Carbohydrates, lipids, proteins, and nucleic acids |
front 3 What is a carbohydrate and give a characteristic of it. | back 3 They provide substrates for cellular respiration and lead to energy production. Their basic building blocks are sugars(monosaccharides) |
front 4 What is a lipid and give a characteristics of it. | back 4 Lipids(fat) are compounds that are insoluble in water and are used for energy and building cellular structures. |
front 5 What is a protein and give a characteristic of it. | back 5 A protein is a complex molecule made up of amino acids. The bond between to amino acids are called a peptide bond. |
front 6 What is a nucleic acid and give a characteristic of it. | back 6 A nucleic acid is essential to all forms of life. They are composed of nucleotides such as DNA and RNA. |
front 7 What are organic compounds? | back 7 Substances that contain carbon, hydrogen, and oxygen |
front 8 What is a nucleotide? | back 8 The basic structural unit of nucleic acids |
front 9 What are indicators? | back 9 Special chemicals that change color (that is visible to the naked eye) in the presences of specific chemical substance. |
front 10 What does the Benedict's test do? (know the colors it produces) | back 10 It detects reducing sugars. |
front 11 What does the Lugol's test do? | back 11 Identifies the presence of starch. |
front 12 What is Sudan VI? | back 12 A fat soluble dye that is water hating. |
front 13 What is hydrophobic? | back 13 Water hating |
front 14 What is hydrophilic? | back 14 Water loving |
front 15 What is a "grease spot"? | back 15 The basis of a very simple test for fats |
front 16 What does a ninhydrin reagent test for? | back 16 Alpha amino acid and proteins contain free amino and acid groups. |
front 17 What is a free amino acid? | back 17 One that is not joined to another amino acid in a chain or ring. |
front 18 What does the Biuret test detect? | back 18 The presences of proteins and short peptide chains of amino acids |
front 19 What sugar does not react with benedict's reagent. | back 19 Sucrose (fructose and glucose) |
front 20 All living organisms are made up of what... | back 20 cells |
front 21 True or false. Organisms can either be simplistic(single cell) or complex and multicellular. | back 21 True |
front 22 What are organelles? | back 22 A specialized subunit in cells that have a specific function. |
front 23 Cells are categorized based on what? | back 23 Membrane bound(eukaryotic) or free floating (prokaryotic) |
front 24 What are prokaryotic cells? | back 24 They are the most basic cellular form and have no membrane bound organelles. (Most organelles are bacteria) |
front 25 What does prokaryotic means? | back 25 Before the formation if the nucleus. |
front 26 The vast majority of organism are what? | back 26 Heterotrophic |
front 27 What does heterotrophic mean? | back 27 They require external sources of food |
front 28 What shapes do bacteria come in. | back 28 round(cocci), rod-shaped(bacilli), and spiral(spirilla) |
front 29 What is morphology? | back 29 The form and structures of animals and plants. |
front 30 Photosynthetic bacteria can do what? | back 30 Can produce their on food |
front 31 To view the basic shapes of cells what do we need to use? | back 31 A compound light microscope with oil immersion 100x lens. |
front 32 How do you classify bacteria? | back 32 Using Gram's stain |
front 33 What are the 2 groups bacteria can be classified in? | back 33 Gram positive or gram negative |
front 34 What is cyanobacteria and where is it located? | back 34 A unique type of photosynthetic prokaryote that contains chlorophylllla. It is found in the thylakoid membranes. |
front 35 What is subculturing? | back 35 When bacteria is transferred form one medium plate to another. |
front 36 What is a flagella? | back 36 A flagella is a hairlike structure that are used for locomotion(movement) |
front 37 What is the function of DNA in a cell? | back 37 DNA carries hereditary information in many organism. |
