What stage of cellular respiration yield the most ATP?
Electron transport chain. During electron transport chain 34 ATP molecules are produced whereas glycolysis and citric acid cycle yield 4 ATPs (2 during glycolysis and 2 during citric acid cycle).
What products of the citric acid cycle are needed for the electron transport chain?
NADH and FADH2 are the main products of the citric acid cycle that are needed for the electron transport chain. These molecules carry high-energy electrons to the electron transport chain, where they donate the electrons to generate ATP through oxidative phosphorylation.
What events take place within the mitochodrial membrane?
ETC---Electron transport chain
When a poison such as rotenone blocks the electron transport chain glycolysis and the citric acid cycle soon grind to a halt as well because?
Rotenone inhibits complex I of the electron transport chain, disrupting the flow of electrons and the generation of ATP. This affects the regeneration of NAD+ and FADH2, which are necessary for glycolysis and the citric acid cycle to continue. Without a functioning electron transport chain, these processes cannot efficiently produce ATP, leading to a halt in glycolysis and the citric acid cycle.
Which steps in aerobic cellular respiration require oxygen?
The citric acid cycle and the electron transport chain are the steps in aerobic cellular respiration that require oxygen. Oxygen is the final electron acceptor in the electron transport chain, where it helps generate ATP by facilitating the transfer of electrons from NADH and FADH2 to oxygen.

What are the 3 stages of aerobic repiration?

What are three phases of the cellular respiration process?
Glycolisis Citric acid cycle(Krebs) electron transport chain
What two parts of cellular respiration require oxygen?
The two parts of cellular respiration that require oxygen are the Krebs cycle (citric acid cycle) and the electron transport chain. Oxygen is the final electron acceptor in the electron transport chain, which is essential for the production of ATP.
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from?
Most of the NADH that delivers high-energy electrons to the electron transport chain comes from the citric acid cycle (Krebs cycle) during cellular respiration. This cycle generates NADH as a byproduct when converting acetyl-CoA to CO2, which is then used to produce ATP in the electron transport chain.
What are the 3 metabolic pathways and which are aerobic?
The three metabolic pathways are glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain. Glycolysis can occur in both aerobic and anaerobic conditions. The citric acid cycle and electron transport chain are aerobic processes that require oxygen to generate ATP efficiently.
What is the Order of aerobic cellular respiration electron transport chain-glycolysis-preparatory reaction-citric acid cycle?
The correct order is glycolysis, preparatory reaction, citric acid cycle, and then the electron transport chain. During these steps, the cell gradually breaks down glucose to produce ATP, the cell's main energy source. Each stage in the process plays a specific role in extracting energy from glucose molecules.
What are the three stages of cellular respiration in order?
The three stages of cellular respiration in order are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Glycolysis takes place in the cytoplasm, the citric acid cycle occurs in the mitochondria, and oxidative phosphorylation takes place in the inner mitochondrial membrane.
