MICROBIO 4000 EXAM #1 REVIEW QUESTIONS AND ANSWERS, GRADED A+ 1. Light reactions in phototrophs - -- Capture light energy and convert it to ATP and/or NADPH via photophosphorylation 1. Substrate-Level Phosphorylation - -- intermediate in catabolism provides the energy directly to ADP EX. glycolysis and krebs 2 components of Peptidoglycan - -- glycan - tetrapeptide 2 types of energy - -- Potential: stored energy (e.g. chemical bonds, concentration gradient) - Kinetic: energy of movem...

Heterochromatin - Regions in chromosome where fibers are highly condensed Few genes - resistant to transcription by not completely exempt Concentrated in centromeres and telomeres What is a simple genome and which type of cell has one? - Codes for fewer proteins then a complex genome, prokaryotes Plant cell walls were.... - Reacquired after eukaryotes lost cell walls when they diverged from prokaryotes Genes - Regions of DNA transcribed into any type of RNA What are RNPs? Examples - Ribo...

Conjugation - Answer-DNA from a donor cell is transferred to an adjacent recipient cell Transformation - Answer-DNA released into the environment by dead cells is taken up by a recipient cell Transduction - Answer-DNA is transferred from a donor to a recipient cell by a virus Three domains - Answer-Eukarya Archaea Bacteria Eukarya and Archaea are more closely related Archaeon Enviornments - Answer-Many archaea are extrelmeophiles carbon fixation and respiration - Answer-Bacteria and arch...

BIOLOGY MAJOR FIELD TEST 2024 QUESTIONS WITH CORRECT ANSWERS ALREADY PASSED AND VERIFIED Adaptive vs. Innate Immune Response - CORRECT ANSWER Adaptive - "specific response" Has immunological memory Later response (3-7 days) Uses B and T cells Effectiveness increases with exposure Innate- "nonspecific response" 1st line of defense Response within 12 hours Lacks immunological memory Mutualism - CORRECT ANSWER Benefit to both partners Normally partners cannot live seperately C...

Phototrophs - Organisms that capture energy from sunlight Heterotrophs - Organisms that obtain organic carbon compounds by consuming other organisms Autotrophs - organisms that make their own organic carbon from inorganic sources Chemotrophs - Organisms that derive their energy directly from organic molecules such as glucose First law of thermodynamics and relation to energy - Energy is neither created nor destroyedenergy of the starting materials for a reaction will equal the sum of energi...

FAU BROOKS BIODIVERSITY UNIT 1 EXAM LATEST UPDATE GRADED A+ T or F: We have proven how life arose? FALSE ! Haldon-Oparin Hypothesis life arose spontaneously from methane, ammonia, water & energy sources Milley-Urey experiment Tested Haldane-Oparin hypothesis Contemporary scientist think that methane & ammonia were likely ABSENT in early atmosphere Organic molecules: CO, CO2, H2 (not much), N2 and H2O Panspermia idea that organic molecules were brought to earth by meteorites/aster...

What are the two types of metabolism? correct answer: Catabolism and anabolism Catabolic metabolism correct answer: -Use large molecules to break them down into small molecules and produce energy -Product of one reaction serves as the substrate for the next -Usually molecules that are rich in C N O because those are essential for microorganisms Anabolic metabolism correct answer: Small molecules and energy to synthesize large molecules Amphibolic pathways correct answer: glucose t...

Define 'energy'. - -The capacity to do work (to cause change) Compare potential energy and kinetic energy. Classify different energy forms into one of these two categories. - Potential Energy = stored energy 1. Chemical Energy: E stored in bonds of atoms and molecules 2. Concentration Gradient: concentration differences across membrane 3. Gravitational Energy: E of position or place 4. Stored Mechanical Energy: E stored in objects by application of a force Energy Energy = motion 1. Ele...
