◍ What is metabolism?.
Answer: All chemical reactions that occur within a cell.
◍ What is a microorganism?.
Answer: Living organisms that are not visible to the naked eye
◍ What cell type was the first on Earth?.
Answer: Prokaryotic Cells
◍ What is catabolism?.
Answer: The breakdown of molecules to release energy.
◍ What is anabolism?.
Answer: The building of complex molecules using energy.
◍ Which type of microbe is not a living microorganism?.
Answer: viruses
◍ How are organisms named using binomial nomenclature?.
Answer: The first word is the name of the genus, and the second word is the
species name
◍ What are the three domains of life?.
Answer: Bacteria, Archaea, Eukarya
◍ What are some distinguishing features of Bacteria and Archaea?.
Answer: They are both prokaryotes, unicellular, and do not contain
membrane-bound organelles
◍ What molecule stores and transfers energy in cells?.
, Answer: ATP (Adenosine Triphosphate).
◍ What are some distinguishing features of Eukarya?.
Answer: They are eukaryotes, can be either unicellular or multicellular, and
do contain membrane-bound organelles.
◍ How did the swan neck flask disprove spontaneous generation?.
Answer: The first step Louis Pasteur took to disprove "spontaneous
generation" was demonstrating that air contains microorganisms. He did this
by filtering air through a cotton plug that trapped the microorganisms, then
examined them with a microscope. He found that the microorganisms
looked identical to those that other scientists had been describing when they
studied sterilized broth. He also demonstrated that sterile broths in specially
constructed swan-neck flasks stayed sterile even when open to room air. He
found that only when the flasks were tipped would microorganisms enter the
broth and grow, and when they settled in the bends of the flask neck, they
never reached the broth. This ended arguments about the unheated air or the
broths containing a "vital force" that was necessary for spontaneous
generation.
◍ What microbe is responsible for Bubonic Plague?.
Answer: Yersinia pestis
◍ What microbe is responsible for Tuberculosis?.
Answer: Mycobacterium tuberculosis
◍ What microbe is responsible for Smallpox?.
Answer: variola virus
◍ How does ATP store energy?.
Answer: In high-energy phosphate bonds that release energy when broken.
◍ What microbe is responsible for Cholera?.
Answer: bacterium vibrio cholerae
◍ What infection is considered eradicated?.
Answer: Smallpox
, ◍ What is substrate-level phosphorylation?.
Answer: Direct transfer of a phosphate from a substrate to ADP.
◍ Who was John Needham?.
Answer: A Scottish clergyman who coined the term "spontaneous
generation". Thought that there was a "life force" present in non-living
matter.
◍ What is oxidative phosphorylation?.
Answer: ATP made using the electron transport chain and chemiosmosis.
◍ Who was Louis Pasteur?.
Answer: - French chemist- Experimented with broth & growth of microbes-
Disproved spontaneity; germ theory of disease- Germ Theory of Disease:
specific diseases are caused by specific microbes. - Created Pasteurization to
kill microbes
◍ Who was Antonie van Leeuwenhoek?.
Answer: Dutch cloth merchant that created the single-lens microscope. Was
known as the Father of Bacteriology and Protozoology.
◍ What is photophosphorylation?.
Answer: ATP generated using light energy during photosynthesis.
◍ Who was John Snow?.
Answer: - English physician- Mapped occurrences of cholera in London-
Revealed cholera was concentrated in areas in need of sewage treatment &
pure water supply- "Father of Epidemiology"
◍ Name the three biochemical pathway structures..
Answer: Linear, branched, and cyclic.
◍ What is a substrate?.
Answer: The reactant an enzyme acts upon.
◍ Who was John Tyndall?.
Answer: - An English physicist- Discovered spores- Found that some
microbes have very high heat resistance and are difficult to destroy
