Cell Growth Flashcards
Macronutrients
CNPHOS
Essential cations
Mg, Fe, k, Ca
Micronutrients
Cobalt, copper, manganese, molybdenum
What is carbon
Central macronutrient to all living things
Heterotrophs
Acquire carbon from other living organisms for assimilation and energy production. Polysaccharides
Autotrophs
Acquire carbon from CO2
Phototrophy
Chemical reactions driven by light for energy
Chemotrophy
Metabolism of high energy organic compounds for energy
Where is energy stored
High energy molecules like ATP or in electrochemical membrane potentials like PMF
Generation time
Length of time from one generation to the next
Lag phase
Cells are preparing for growth, detecting their environment, expressing genes and synthesizing cellular components
Log phase
Cells are growing at the maximum K possible under specified growth conditions
Stationary phase
Growth levels off and the rate at which cells divide and die are equal to each other
Death phase
The death rate exceeds K subpopulations may arise and survive that have adapted to the death phase environment
Abiotic factors
Temperature, pH, and osmolarity have a Lahore influence on prokaryotic cell growth
