Exam 1 Review Flashcards
(Ch 2) What is VAERS and who can report it?
Vaccine Adverse Event Reporting System; anyone may submit a report on an adverse reaction to a vaccine.
(Ch 1) Dr. Blehert took healthy bats into his laboratory. He exposed some of them to the fungus suspected of causing white-nose syndrome (WNS). The rest of the bats were not exposed to the fungus but were otherwise kept under the same environmental conditions. This method of manipulating one or more aspects of the natural world in a repeatable manner and with the intention of answering a specific question is called a(n)…
controlled experiment
(Ch 3) A solution with pH = 5 is ______ than a solution with pH = 7.
100 times more acidic
(Ch 3) What is true about the properties of water at different temperatures?
Water molecules in ice are spaced farther apart from one another than water molecules in liquid.
(Ch 3) Which of the following is NOT a type of monomer?
A. Nucleotide
B. DNA
C. Monosaccharide
D. Amino acid
B. DNA
(Ch 3) In order to determine the atomic mass of an atom, one needs to know…
the number of protons and neutrons
(Ch 3) Hydrogen bonds are…
weak chemical bonds that hold separate molecules together.
(Ch 3) Sodium chloride (NaCl) dissolves well in water because…
it has charges that allow it to interact with water.
(Ch 4) Osmosis is a form of…
simple diffusion
(Ch 4) This structure is primarily responsible for the enzymatic breakdown of large molecules in the cell.
Lysosome
(Ch 4) Molecules sometimes move across a plasma membrane by passing through channel proteins or with the help of transport proteins. If no energy is used by the cell during this process, the process is called…
facilitated diffusion
(Ch 5) The electrons that are released by the splitting of H20 molecules during photosynthesis ultimately end up in…
NADPH
(Ch 5) The Calvin cycle is driven by _____________ that convert CO2 into sugars.
enzymes
(Ch 5) During cellular repsiration, __________ is the step that produces the greatest number of ATP molecules.
oxidative phosphorylation (80%)
(Ch 5) If you consider the combined process of photosynthesis and cellular respiration, the electrons found in H2O at the beginning of the light reactions end up attaching to__________ during respiration.
O2 to make new H2O
(Ch 5) Anabolism usually __________ energy to produce polymers, whereas catabolism __________ energy to produce monomers.
requires; releases
(Ch 5) The protons moved by the proton pump during the light-dependent reactions of photosynthesis come from…
H2O
(Ch 5) In a multistep metabolic pathway, the products of the first enzyme-catalyzed reaction typically…
are the substrates for the next reaction in the pathway
(Ch 5) Which of the following is closely associated with mitochondria?
A. Krebs cycle
B. Glycolysis
C. Calvin cycle
D. Thylakoid
A. Krebs cycle
(Ch 5) During which cellular process is ATP NOT released?
Calvin cycle
(Ch 5) Which of the following ultimately provides the O2 used during the process of oxidative phosphorylation?
A. Light-dependent reactions of photosynthesis
B. Krebs cycle
C. Carbon fixation
D. Calvin cycle of photosynthesis
A. Light-dependent reactions of photosynthesis
(Ch 6) Replication of a cell’s genetic material occurs during…
S phase
(Ch 6) A characteristic that distinguished meiosis from mitosis is…
the total number of chromosomes present in daughter cells.
(Ch 6) The nuclear envelope breaks down during which phase of mitosis?
Prophase
(Ch 6) During which phase of mitosis do replicated chromosomes line up at an invisible plane along the center of the cell?
Metaphase
