18 Questions
Where do dark reactions occur in the process of photosynthesis?
Stroma
What is the primary function of ATP and NADPH molecules in the dark reactions?
To convert CO2 into glucose
What is the term for the process of converting ADP molecules back into ATP molecules?
Cellular respiration
What is the principle of energy conservation stated in the context of cellular respiration?
Energy can be transferred and transformed, but not created or destroyed
What is the byproduct of energy transfer or transformation in the universe?
Increased entropy
What is the process of studying the interaction of metabolic pathways called?
Metabolomics
What is the purpose of oxygen in the electron transport chain?
To accept electrons and H+ ions, forming water
What is the maximum ATP yield from the electrons carried by NADH and FADH2?
3 ATP/NADH and 2 ATP/FADH2
What is the result of the protons flowing back into the matrix through ATP synthases?
The generation of energy to produce ATP
What is the process by which the energy from the electron transport chain is used to generate ATP?
Oxidative phosphorylation
Where do the electrons carried by NADH enter the electron transport chain?
At the flavoprotein molecule
What is the name of the process by which a proton gradient is used to generate ATP?
Chemiosmosis
What is the net gain of ATP molecules during glycolysis?
2 ATP
What is the purpose of the electron carrier NAD+ in glycolysis?
To accept high-energy electrons and transfer them to NADH
What is the result if a cell generates large amounts of ATP from glycolysis?
The cell's available NAD+ molecules become filled up with electrons
Why did glycolysis evolve before the other stages of cellular respiration?
Because there was no oxygen in Earth's atmosphere when life first evolved
What happens to the 2 remaining pyruvic acid molecules in the presence of oxygen?
They enter the Krebs cycle
What is the significance of glycolysis being a fast process?
It allows cells to produce thousands of ATP molecules in a few milliseconds
Learn about the process of oxidative phosphorylation in cellular respiration, including the role of electron transport chains and the generation of ATP. Understand how NADH and FADH2 contribute to ATP production and calculate the maximum output of ATP.
