Cellular Respiration Vocab Flashcards
Q3 BIOLOGY
Calorie (little c)
Define.
A unit that measures the energy required to raise 1g of water by 1 degree C.
Calorie (Big c)
Define.
A unit that measures the energy required to raise 1000g of water by 1000 degree C.
Cellular Respiration
Define.
A process in the mitochondria where glucose is turned into energy.
Aerobic
Define.
To require oxygen.
Anaerobic
Define.
To not require oxygen.
Glucose
Define.
A simple sugar essential for living organisms.
Glycolysis
Define.
The breakdown of glucose.
NAD+
Define.
A molecule important for metabolism (Nicotinamide Adenine Dinucleotide).
What is the purpose of the Krebs Cycle? What does it do?
A stage of cellular respiration in which glucose and oxygen are converted to carbon dioxide.
Matrix
Define.
Dynamic gell found in the cytoplasm of a cell that surrounds all organelles.
Fermentation
Define.
Conversion of sugars into ethanol.
What is the difference between ALCOHOLIC fermentation and LACTIC ACID fermentation.
ALCOHOLIC fermentation converts sugars into cell energy, ethanol and carbon dioxide.
LACTIC ACID fermentation converts sugars into cell energy and metabolite lactate (Lactic acid).
Photosynthesis
Define.
The process plants go through to make their food/energy.
What is the chemical formula for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2.
What is the chemical formula for glucose?
C6H12O6
(Six carbon, twelve hydrogen, six oxygen)
How many CO2 and H2O particles are needed for photosynthesis to produce glucose and oxygen?
6 each.
6CO2 + 6H2O → C6H12O6 + 6O2.
What is the chemical formula for Cellular Respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
What is ATP?
The energy currency of the cell.
What is PRODUCED by the Krebs cycle?
Six carbon dioxide molecules (6CO2), six water molecules (6H2O), and cell energy (ATP).
