Aerobic/anaerobic respiration Flashcards
cellular respiration
getting ATP out of the food consumed
Aerobic respiration
uses oxygen, gas, and glucose to produce ATP (ex: humans and plants)
Anaerobic respiration
does not use oxygen or gas to produce ATP
Aerobic respiration equation
C6H12O6 + 6 O2 –> 6 H2O + 6 CO2 + 36 ATP
breathing
breathing is a way of getting a product (O2) into our bodies and getting rid of waste products (CO2) while both gases diffuse in and out of the blood stream
Breathing - pathway in
-breathe in O2 to lungs
O2 diffuses into
- bloodstream across air sacs in the lungs
- circulatory system carries O2 to your cells
- O2 diffuses into the mitochondria (site of respiration)
breathing - pathway out
- opposite
- CO2 diffuses out the cells into the bloodstream
- circulatory system carries CO2 to your lungs
- CO2 diffuses out of bloodstream across air sacs in the lungs
- breathe out CO2
what happens to the glucose plants produce when they respire?
Plants respire about 1/2 of the glucose they produce; the glucose they keep is used to produce starch, cellulose, organic molecules
Plants absorb more ___ in photosynthesis than they release in respiration and they release more ___ than they consume
CO2, O2
What are the three parts of cellular respiration?
Glycolysis, Citric Acid cycle, and Electron Transport Chain (ETC)
glycolysis
process that occurs in the cytoplasm where 2 ATP, NADH, and 2 pyruvate molecules are produced
Citric Acid Cycle
Process that occurs in the mitochondria (eukaryotes) or cytoplasm (prokaryotes) where pyruvate is oxidized (release of CO2) and NADH, ATP, and FADH2 is produced
Electron Transport Chain
Process that transfers electrons from NADH, FADH2 to create proton (H+) gradient
