cellular metabolism a controlled set of biochemical reactions that occur in living organisms in order to maintain life enzyme a protein, or group of proteins, that catalyze (speed up) chemical reactions/is not consumed during the reaction and can be used repeatedly by the cell cofactor a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions/serve as regulators of chemical reactions: in their absence, enzymes are inactive while in its presence enzy...

True or False: Because the genome is contained within an enclosed space, (much like the nucleus of a cell) viruses are classified as eukaryotic - False. Viruses are neither eukaryotic nor prokaryotic Describe the two basic components of a virus (short answer) - A virus has 1. genomic material comprised of either DNA or RNA and 2. a capsid, a membrane-like protective structure that contains the genetic material, similar to the nucleus of a eukaryotic cell The _____ surrounds the capsid of so...

What is the total magnification of a sample imaged with a 60x objective and a 10x eyepiece? (short answer) - 60 x 10 = 600x magnification True or False: A cell that is adherent, flat, and unstained is easily identified using bright field microscopy - False. Adherent, flat cells are almost invisible due to the limits on both resolution and contrast Which of the following could be seen clearly by the unaided eye? (multiple choice) - Protozoa with diameter of 150um and skin cell with diameter ...

Define the concept of universal precautions (short answer) - Universal precautions means any and all samples, whether known or unknown, are to be treated as potentially hazardous (or pathogenic) materials List at lease 3 observations a researcher would be sure to note while assessing and unknown microbial sample (short answer) - Need to note: 1. Size and shape 2. Any observable motility 3. Gram status (positive or negative) While observing an unknown sample of limited amounts, a research...

micrometer - one millionth of a meter nanometer - one billionth of a meter resolution and contrast - two critical factors that influence our ability to see an object resolution - the distance between two objects at which the objects still can be seen as separate greater - the closer two objects are to each other the __________________ the resolution requirement contrast - the difference in light absorbance between two areas (objects) lower - the ________________ the contrast between an ob...

A nanometer is defined as: - 10-9 A nanometer is defined as one-billionth of a meter True or False: A nanometeris longer than a micrometer - False. A nanometer is 1,000 times smaller than a micrometer. Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. - Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low resolution means two (or more) objects may appear as one. *Cont...

Microorganism - Single cell (bacteria, archaeons, fungi, protozoa, algae) Virus - Not living, not considered microorganisms, considered microbes Microbes - Include microorganisms and viruses, can be advantageous or harmful Cell - Smallest, most basic biological unit of life All cells are compromised of - Macromolecules (building bloacks) Four main types of macromolecules found ing cells - Proteins, nucleic acids, lipids, and polysaccharides Proteins - Comprised of amino acids, facilitate ...

Microbiology is the study of what? - Microbiology is the study of microbes (microorganisms and viruses) and their biological processes. What is the smallest biological unit of life? - A Cell What is a macromolecule? - A macromolecule is classified as a complex molecule that is composed from smaller subunits. What are the four main types of macromolecules? - 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids What various functions do proteins have in a cell? - Proteins may facilitat...
