Total questions: 10
Worksheet time: 5mins
Metabolic pathway is ___
chain of chemical reactions in which the product of one reaction serves as substrate for the next
processes in which the energy derived from catabolism is used to build large organic molecules
processes to release the energy stored in their chemical bonds
lowering the energy of activation
Anabolism is
metabolic processes in which the energy derived from catabolism is used to build large organic molecules from smaller ones
molecules are broken down through metabolic processes to release the energy stored in their chemical bonds
time for population to double
rate of cell death exceeds the rate of cell division
During decline phase on microbial growth,
cells begin to encounter environmental stress
microorganisms, like animals, can obtain energy from lipids
amino acids are deaminated
the environment has become difficult for living
Fatty acids are oxidized by beta oxidation
hydrolyzed into individual amino acids by proteolytic
as catalysts for metabolic reactions
results in the release of acetyl CoA then enters the Krebs cycle
through metabolic processes to release the energy stored in their chemical bonds
The uses of energy by microorganisms is for
Bioluminescence
Fly to the air
evolve to become plankton within a day
Microbial growth is
Increase in cell size, not number of cells
Increase in number of cells, not cell size
technique used to grow microorganisms or cells in lab
rate of cell death exceeds the rate of cell division
The rate of cell division decreases, and the older cells begin to die.
Log phase
Lag phase
Stationary phase
Decline phase
During third phase, bacteria begin to encounter environmental stress because of followings, except
they mutated and become plankton, not fit in petri dish anymore
nutrients decreased
metabolic waste accumulated
pH of the medium becoming to acidic for them to thrive
First phase of bacterial growth phase is
Log
Stationary
Decline
Lag
One of significance of energy capture is
yields 19 glucose molecule
yields 38 glucose molecule
yields 68 glucose molecule
yields 8 glucose molecule
