University of Houston BCHS 3304 Exam 1 || 100% Verified
Solutions.
Natural Laws correct answers Conservation of mass and energy
laws of thermodynamics
laws of chemical kinetics
principles of chemical reactions
axioms correct answers energy is converted to work
catalytic chemical transformations
assembly of molecules with great complexity from simple subunits
complex molecules combine to form supra molecular components and become a cell
store and pass instructions for the assembly of all future generations from nonliving beginnings
in the beginning correct answers h2 began he, universe is 15-20 billion years old
stars exploded, making the high numbered atoms
biochemistry is studying life at the chemical level
oldest fossil is from stomatolite in western Australia 3.5 billion years old
common themes of life correct answers single cell becomes multi cell, evolution increases
diversity
organic compounds in organisms are products of biological activity--limestone and coral reefs
biomolecules experience natural selection and have the same chemical properties that non-living
matter molecules do! so physics & chemistry define life.
6 issues correct answers 1. what are chemical and 3d structures of biomolecules?
2. how do these biomolecules interact together?
3. how does the cell make and use biomolecules?
,4. how does energy conservation work and how is it used in the cell?
5. what systems exist to organize biomolecules and conduct functions using them?
6. how is genetic information stored, transmitted, and expressed?
prokaryotes correct answers small asf (10um) and no membrane bound nucleus but nucleic
matter just floats around in the cytoplasm
biochemical breakdown correct answers organism --> organ --> tissue --> cell --> organelle -->
supramolecular assembly --> macromolecule
life from the sea correct answers h2o is thought to be the key to understanding macromolecule
behaviors, and it's the solvent of life and part of every transformation
lipid membranes and other insoluble compounds still have natures and functionality that's related
to water activity and interactions
living organisms are made of lifeless molecules, but collective behavior and interactions create
properties that define life. no vital force or vitalism.
biochemistry has pushed science forward but it's primarily concerned with the wonder of life!
parts of the cell correct answers nuclear membrane, nucleus, nucleolus
centrioles
golgi apparatus
chromatin
ribosomes
ER smooth/rough
lysosomes
cell membrane
mitochondrion
vacuole
, specific biochemical adaptations correct answers range of life, hot springs, subduction zones,
artic tundra, antarctic dry fields, animal intestines, college dormitories
living organisms correct answers complicated structures and super organized
-intricate internal structures and lots of complicated molecules
-proteins, DNA, RNA, starches, lipids, etc
-inanimate objects are mixtures of simple compounds
living organisms pt. 2 correct answers extract, transform, store, and use ENERGY
living things can pull energy from surroundings
chemical: chemoautotrophs or lithoautotrophs--reaction that begins with H2S, ends with iron,
water, and carbon dioxide
sunlight: phototrophs--photosynthesis
energy building correct answers energy creates and helps maintain structures
mechanical energy--muscles
chemical energy--electric eels
osmotic energy--plant turger
light energy--bioluminescence
living things correct answers self-replication and self assembly is fundamental to living things
inanimate matter does not do this much multiplicative replication, and it's an almost perfect
process
a crystal at equilibrium will grow but life at equilibrium is death
life is a bunch of relationships that characterize nature, function, and interaction of biomolecules
family trees of life correct answers urkaryotes
-eukaryotic cytoplasms
