Which step of glucose metabolism generates the most ATP?
Glycolysis takes place in the cytoplasm, whereas the Krebs cycle and the electron transport chain, which generate the largest amounts of ATP during cellular respiration, take place in the mitochondria.
Which process releases the greatest amount of ATP?
Which step produces the most ATP quizlet?
Oxidative phosphorylation produces more ATP has the electron carriers NADH and FADH2, which can supply more molecules of ATP . Since there are lots of both carriers, they can produce significantly larger amounts of ATP.
Which of the following metabolic pathways produces the most ATP?
Most of the ATP in cellular respiration is produced by the process of chemiosmosis.
Does photosynthesis produce ATP?
These are the “Light Phase Reactions” of photosynthesis, which produce two high energy chemical products, namely NADPH and ATP. … And in the end, the plants have utilized the energy of sunlight to produce glucose (and ultimately other carbohydrates, proteins and fats) and oxygen from water and carbon dioxide.
How much ATP is produced from glycolysis?
Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
Which process releases the highest amount of energy?
In the process of glycolysis only 2 molecules of ATP are produced. Maximum energy is released, when the reduced coenzymes produced in the process of Krebs cycle are oxidised in the process of oxidative phosphorylation in electron transport chain.
Which process releases energy from food by producing ATP in the absence of oxygen?
How can cells release energy without using oxygen?
Fermentation is an energy releasing process that does not require oxygen. During fermentation, cells release energy from food without using oxygen. The disadvantage of fermentation is that it releases far less energy than cellular respiration.
Which of the following produces the most ATP?
So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.7 мая 2019 г.
What is the most direct source of energy to convert ADP to ATP?
In chemiosmotic phosphorylation, what is the most direct source of energy that is used to convert ADP + inorganic phosphate to ATP? H+ concentration across the membrane holding ATP synthase.
What is the role of ATP synthase?
The ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
How much ATP does photosynthesis produce?
Glucose combines with oxygen (oxidation), forming carbon dioxide, water and 38 molecules of ATP.
What type of metabolic pathway requires oxygen?
Why does etc produce the most ATP?
During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP. The most vital part of this process is the electron transport chain, which produces more ATP than any other part of cellular respiration.
