cellular respiration

chapter 5

QuestionAnswer
aerobic with oxygen
anaerobic without oxygen
NAD an electron carrier that converts to NADH
FAD an electron carrier that converts to FADH2
Cellular Respiration a way for cells to make energy when oxygen is present, and is the transformation of the chemical energy in food into energy for cells
Fermentation a way for cells to make energy when oxygen is not present, results in less energy
Equation for Cellular Respiration C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP( energy)
Decomposition Reaction taking a larger molecule and making it into smaller molecules
Decomposition a pathway that provides the energy cells need to function occurs with or without oxygen
Breathing CR uses O2 to help harvest energy from glucose and produces CO2 in the processes which is then exhaled
Where is Glycolysis preformed the cytoplasm
Where is the Kreb's Cycle preformed the matrix of the mitochondria
Where is the Electron Transport System/Chain preformed the cristae of the mitochondria
how many ATP come from one glucose molecule in CR 38
what goes into Glycolysis 2 ATP, glucose
what is formed in Glycolysis 2 pyruvate, 2 ATP 2 NADH
what goes out of Glycolysis and where does it go 2 pyruvate into the krebs cycle , 2 NADH to the ETC
Pyruvates (Pyruvic Acid) are always converted into Acetyl coenzyme A
What fuels CR glucose and oxygen
How many ATP come from Fermentation 2
Pre Kreb's Cycle where pyruvates change to acetyl COA
what goes into the Kreb's Cycle acetyl COA
what is formed in the Kreb's Cycle 2 ATP, 2 FADH², 6 NADH, CO2
what goes out of the Kreb's Cycle and where does it go 2 FADH² into the ETC, 6 NADH into the ETC, 2 ATP
what goes out of the Pre Kreb's Cycle and where does it go CO2 into the atmosphere, 2 NADH into the ETC
what goes into the ETC O2, 2 FADH², 10 NADH
how many ATP form from one NADH 3
haw many ATP form one FADH² 2
what goes out of the ETC H2O, 34 ATP
how many ATP come from all 3 stages 38
where is Fermentation preformed the cytoplasm like glycolysis
what is oxygen's role in CR oxygen determines if respiration occurs aerobically or anaerobically, also how many atp are produced bc it could be 38 or 2
where is most ATP made ETC
what are other sources of sugar besides glucose that can help make ATP carbs, fats, proteins
Biosynthesis grabs electron carriers from glycolysis and krebs cycle and are used as building blocks for other molecules your body needs consists of many metabolic pathways,
actin thin filaments
myosin thick filaments
what are filaments threadlike object or fiber
when does the contraction of a muscle occur when actin filament smove over the myosin filaments
what is ATP's role in muscle contraction it is used to release myosin head from actin and to rest the myosin head in position to start the cycle over again
slow twitch fibers aerobic, more endurance, high resistance to fatigue, helpful in long distance running, swimming, biking etc. are dark and have many mitochondria
fast twitch fibers strength, quick fatigue, weight lifting, springing, are light and have few mitochondria
where does mitochondrial disease cause the most damage brain, heart, skeletal muscles, kidney, endocrine system, respiratory system.
heat CR releases some energy as this which helps keep our internal temp constant, some plants produce enough that they release an odor
exergonic energy exits
alcoholic fermentation pyruvic acid break down, uses yeast which can ferment w or w/o O2, converts pryvaute to CO2 and ethanol wihle oxidizing NADH to NAD+
lactic acid fermentation produces lactic acid, co2 and 2 atp happens because there is no 02 supply after glycosis happens in muscles
what are the products of alcoholic fermentation ethanol co2 NAD+ 2ATP
hydrolysis of ATP add a molecule of water to break a bond
dehydration of ATP loose a water molecule to make a bond between ADP and P
CR production of heat releases energy as heat and helps keep our internal temps constant
how is pyruvic acid made from broken down glucose
how is photosynthesis different from cellular respiration the products of cellular respiration are the reactants of photosynthesis and vise versa
oxygen's role in cellular respiration O2 determines if respiration occurs arobically or aneribically
carbon dioxide role in cellular respiration product of prekrebs and krebs cycle and is released into the atmosphere for use
importance of prekrebs cycle changes 2 pyruvate into 2 acytl CoA which then produces all the electron cariers to later produce the majority of the ATP
what is the electron acceptor in cellular respiration oxygen
