Q&A

• What is the estimated range of ATP production in cellular respiration?

  The estimated range of ATP production from the electron transport chain and chemiosmosis step alone is 26-34 molecules, with a total range of 30-38 ATP, including other contributing steps. Cells can also perform fermentation to produce ATP in the absence of oxygen. Cyanide can block ATP production, highlighting the significance of ATP for cells.

• How does the ATP production process work in cellular respiration?

  The proton pump creates a gradient, and ATP synthase converts protons to ATP. Additionally, oxygen combines with electrons to form water, while variations in ATP production numbers are observed in cellular respiration charts.

• What are the essential steps in cellular respiration?

  The Krebs Cycle and Electron Transport Chain are crucial steps in cellular respiration, producing ATP and utilizing oxygen to drive energy production in eukaryotic cells.

• Can plants perform cellular respiration?

  Yes, plants can conduct cellular respiration in addition to photosynthesis. Non-photosynthetic organisms like humans obtain glucose from a food source to initiate the cellular respiration process.

• Which organisms use aerobic cellular respiration?

  Eukaryotic cells in protists, fungi, animals, and plants utilize aerobic cellular respiration to produce ATP, with mitochondria playing a significant role in this energy production process.

• What is aerobic cellular respiration?

  Aerobic cellular respiration is the process eukaryotic cells use to produce ATP, involving mitochondria and the breakdown of glucose to generate energy.

• What do cells need ATP for?

• 00:00 Cells need ATP for energy. Aerobic cellular respiration is a process eukaryotic cells use to produce ATP.
• 01:21 Eukaryotic cells, including those in protists, fungi, animals, and plants, use aerobic cellular respiration to produce ATP. This process involves mitochondria and the breakdown of glucose to produce ATP.
• 02:41 Plants can perform both photosynthesis and cellular respiration, while non-photosynthetic organisms like humans need to obtain glucose from a food source. The process starts with glycolysis in the cytoplasm, which is anaerobic and yields 2 pyruvate, 2 ATP, and 2 NADH. Pyruvate is then transported into the mitochondria for oxidation.
• 03:56 The Krebs Cycle and Electron Transport Chain are essential steps in cellular respiration, producing ATP and utilizing oxygen in eukaryotic cells.
• 05:19 The proton pump creates a gradient, ATP synthase converts protons to ATP, oxygen combines with electrons to form water, and there are discrepancies in ATP production numbers in cellular respiration charts.
• 06:44 The number of ATP molecules produced per glucose molecule can vary due to several variables. The estimated range of ATP production from the electron transport chain and chemiosmosis step alone is 26-34 molecules, with a total range of 30-38 ATP including other steps. Cells can perform fermentation to produce ATP when oxygen is not available. Cyanide can block ATP production, emphasizing the importance of ATP for cells.
