"Cellular respiration intricately balances energy investment and production, highlighting the complexity of metabolic pathways."
"Oxygen's role in sustaining the Krebs cycle: essential for preventing NADH and FADH2 accumulation."
"That electrochemical potential is then used to fuel a motor that by coupling the flowing of those proteins back into the mitochondrial matrix with the synthesis of ATP."
"Oxygen plays a critical role in our cellular respiration and the production of ATP. At the same time, it has very strong oxidizing properties that can actually damage even biological material."
"When the cells have access to oxygen, this process is very efficient with a lot of energy produced."
"The vast majority of ATP is made in our cells through processes like the citric acid cycle and oxidative phosphorylation. This complex process ultimately results in the production of large amounts of ATP, powering our cells and keeping us alive and active."
"Mitochondria are essential in both heterotrophs and autotrophs."
"The Krebs cycle takes place in the matrix."
"Mitochondria produce ATP energy for cells, the fuel that cells use to get things done."
"Chemiosmosis and the electron transport chain produce ATP."
"The mitochondria... that's where aerobic respiration takes place, with all the proteins on the folded membranes inside."
"About 34% of the energy in a glucose molecule is transferred to ATP during cellular respiration, making roughly 32 ATP."
"The cycle oxidizes organic fuel derived from pyruvate, generating one ATP molecule, three NADH, and one FADH2 per turn."
"The endpoint of all the conversations we have about oxygen and hypoxemia ultimately comes down to how much oxygen gets into the mitochondria."
"Remember that this does occur in the mitochondria, the specialized organelle that we call the powerhouse."
"Red blood cells are circular, biconcave, non-nucleated; they do not have mitochondria, therefore there is no Krebs cycle, no electron transport chain in the red blood cell."
"Mitochondria are the ones that produce energy for the cell."
"The chemical equation for aerobic cellular respiration and photosynthesis are basically the same but in reverse."
"One billion oxygen molecules for one red blood cell, is not insane?"
"Mitochondria are where aerobic respiration happens, providing energy for the cell."
"Photosynthesis generates oxygen and organic molecules which are used in cellular respiration."
"Cellular respiration then generates CO2 and water, which are then used in photosynthesis."
"Aerobic respiration consumes organic molecules as the fuel and oxygen, and yields ATP."
"The net gain for glycolysis is therefore: glucose is oxidized to two pyruvate and two waters, four ATP are formed but two were used, so two net ATP, two NADH molecules."
"The ultimate goal of cellular respiration is to trap that energy to form ATP molecules."
"Cellular respiration is a universal process; all cells must have the ability to harness the energy from organic molecules in a controlled way to make ATP."
"Photosynthesis can be considered an anabolic process, whereas cellular respiration is a catabolic process."
"Fermentation doesn't produce any ATP. It merely recycles the electron carriers. It's glycolysis that makes the ATP."
"The most significant production of ATP happens from the redox reactions that happen in the electron transport chain."
"Cellular respiration is the process by which glucose is broken down into carbon dioxide and water, and you get ATP out of it."
"The flow of protons through ATP synthase drives the formation of ATP from ADP and inorganic phosphate."
"The mitochondria are the powerhouses of the cell."
"The mitochondrion... is breaking down energy-containing molecules to release energy so that the cell has energy to do the work it needs to do."
"Crafted as a visual review of aerobic respiration for high school and university biology education."
"The product of glycolysis, the pyruvate molecule, is the source of carbon and electrons for aerobic respiration reactions inside your mitochondria."
"In a sequence of reaction steps, the pyruvate dehydrogenase enzyme complex generates fuel for aerobic respiration reactions of the citric acid cycle and the electron transport chain."
"Ninety percent of the ATP is generated from the next step in cellular respiration called oxidative phosphorylation."
"Chemiosmosis couples electron transport to ATP synthesis."
"During cellular respiration, most energy flows in this sequence: glucose to NADH to electron transport chain to proton motive force to ATP."
"Redox reactions are at the heart of cellular respiration."
"The reason why you have lungs is because you need oxygen for cellular respiration and you have to get rid of CO2."
"Every NADH that you see is going to go directly to the electron transport chain; do not pass go, do not stop to collect $100."
"Mitochondria within the cells are where the bulk of ATP is generated, the fuel for the cell to perform the bulk of its work."
"Assuming oxygen is available, it goes into the mitochondria and there it will first undergo the transition reaction and then the Kreb cycle and then the electron transport system."
"Cellular respiration is the process by which the energy that is contained in organic molecules can be released."
"The whole purpose of cellular respiration is to produce this gasoline called ATP."
"Cellular respiration occurs in all living things."
"Oxidative phosphorylation happens in the mitochondria and is where we generate the bulk of our ATP."
"The ATP is produced because of the coupling of electron transport to proton transport."
"The whole point of cellular respiration is to release the potential energy that is locked in the food molecules we've eaten and use that energy to make ATP."
"Thyroxine causes more glucose to be used during cellular respiration."
"The citric acid cycle provides us with NADH and FADH2, which are great sources of energy for making ATP."
