Chemoheterotrophs - Study guides, Class notes & Summaries

Organic Nutrient An organism that contains carbon and hydrogen Inorganic Nutrient An organism that does not contan carbon and hydrogen Phototroph An organism that gains energy from light through photosynthesis Heterotroph An organism that must obtain carbon in an organic form - they are dependent on other life forms Chemotroph An organism that gains energy from chemical compounds - this means they eat things. Harvesting energy from the things they eat. Autotroph An organism that g...

cyanobacteria - gram-negative bacteria with a number of unusual traits that photosynthesize in the same manner as plants chemoheterotrophs - An organism that must consume organic molecules for both energy and carbon. AIDS - acquired immune deficiency syndrome antibiotics - Drugs that block the growth and reproduction of bacteria archaea - prokaryotes whose cell walls do not contain peptidoglycan Bacteria - Domain of unicellular prokaryotes that have cell walls containing peptidoglycan ba...

Metabolism - correct answer is all chemical reactions in a cell and includes catabolism and anabolism. Catabolism - correct answer Catabolic pathways generate energy by breaking down larger molecules. Anabolism - correct answer Anabolic pathways require energy to synthesize larger molecules. Heterotrophs - correct answer require organic macromolecules for their carbon source for building blocks (monomers). Chemotrophs - correct answer require energy (ATP) from breaking apar...

What is a Transforming Infection? Virus that alters cell DNA, leading to cancer What is a lysogenic infection? Phage DNA is incorporated into host genome and is passed on to subsequent generations What is a Lytic Bacteriophage Infection? Host cell gets so packed with viruses that is lyses (splits) open and releases mature virions What are the three principle purposes of cultivating viruses? 1.) Isolate and ID viruses in clinical specimens 2.) Prepare viruses for vaccine...

How is Animalia related to other kingdoms? correct answersclosely related to fungi because they're both chemoheterotrophs, both have glycogen as their energy storage. What are the three classes of Annelida? Give examples. correct answersClass Oligochaeta- earthworms Class Polychaeta- polychaetes Class Hirudinea- leeches What are the characteristics of Annelids? correct answers-segmented worms -triploblastic -true coelom -some parasitic, some free-living -marine, terrestrial, fresh...

1 molecule of glucose can generate 38 molecules of ATP via aerobic respiration in prokaryotes. And why is it never the case in reality? - CORRECT ANSWERS--Glucose never generates 38 ATP in reality • The PMF generated from ETC is never used only to generate ATP • Bacteria spend some of their PMF energy to maintain stable ion gradients during extreme changes in external pH and oxygen levels • Bacterial also have other cell processes that use PMF directly. E.g. flagellar rotaAon,...

Principles of Microbiology – Exam Questions with Correct Answers Autotrophs - Answer-Synthesize own energy (self feeders) ex: plants Heterotrophs - Answer-Ingests organic molecules (consumers) ex: animals with food Chemotrophs - Answer-Obtain carbon from inorganic substances Phototrophs - Answer-organisms that get energy from light Chemoheterotrophs - Answer-An organism that must consume organic molecules for both energy and carbon. Cause most infectious diseases - most micro...

PRINCIPLES OF MICROBIOLOGY - EXAM 1 WITH COMPLETE SOLUTIONS 100% Microbiology - correct answer The study of microorganisms Pathogen - correct answer An organism that can infect and cause illness/disease Nosocomial - correct answer hospital acquired infection. ex: MRSA (methycillin resistant staph. aurelis) or UTI from catheter 2 million/year universal precautions Autotrophs - correct answer Synthesize own energy (self feeders) ex: plants Heterotrophs - correct answer Ingests o...

how do bacteria and archaea reproduce? - - binary fission - can divide often short generation time How do the mutualistic microbes in our intestines affect basic human biology? - - gut and intestine microbiomes - disruption can be caused by antibiotics cause in disfunction of systems (ex. Diarrhea) How does nitrogen metabolism work? - nitrogen is used to make amino acids nitrogen fixation: atmospheric N2=>ammonia - Carried out by heterocysts how does transformation work in prokaryotes...
