Lab 6 Flashcards
Cellular respiration
Process of taking high energy organic molecules and converting them into smaller energy packets
glucose -> ATP
aerobic and anaerobic
Aerobic cellular respiration
When oxygen is present, much more efficient, occurs in mitochondria of eukaryotes
Anaerobic cellular respiration
respiration occurs in absence of oxygen, much less efficient
fermentation/lactic acid
Cellular respiration process aerobic
- Glucose goes through glycolysis (2ATP)
- from there aerobic or anaerobic
- (aer).
Krebs cycle - (aer)
electron transport system
(34 ATP)
Cellular respiration process anaerobic
- Glucose goes through glycolysis (2ATP)
- from there aerobic or anaerobic
3(anaer)
ethanol or lactic acid (0ATP)
Aerobic respiration formula
C6H12O6 + 6O2 -> 6H2O + 6CO2 + 36 ATP
Anaerobic respiration formula animals
C6H12O6 -> 2C3H6O3 + 2ATP
lactic acid
Anaerobic respiration formula prokaryotes, plants, fungi, protists
C6H12O6 -> 2C2H5OH + 2 CO2 +2ATP
ethanol
fermentation
Our experiment
Measuring anaerobic respiration in yeast = living org
glucose, sucrose, starch
and effect of temp
Autotrophs
Make their own food
Heterotrophs
Consume food made by autotrophs
Photosynthesis
creates glucose (sugar/energy) rather than break it down
6CO2 + 6H2O + solar energy -> C6H12O6 + 6O2
Ideal Gas Law
PV = NrT
P = atmospheric pressure
V = Volume in liters
N = mols of gas
r = universal gas constant
T = temp (K)
respirometers
measures rate of respiration (traps CO2 and measures)
as O2 molecules are consumed pressure drops
Manometer
used to measure pressure of a gas or fluid
quantifies results from respirometer
