What is the first step in cellular respiration?

The first step in cellular respiration is glycolysis, where glucose is broken down into pyruvate molecules in the cytoplasm of the cell, producing a small amount of ATP and NADH in the process.

What molecule from food enters the mitochondria?

The molecule that enters the mitochondria from food is acetyl-CoA, which is produced during the breakdown of carbohydrates, fats, and proteins through various metabolic pathways in the cell. Once acetyl-CoA enters the mitochondria, it undergoes further processing in the citric acid cycle to generate energy in the form of ATP through oxidative phosphorylation.

What process occurs in the cytoplasm before cellular respiration?

Glycolysis, the breakdown of glucose into pyruvate, occurs in the cytoplasm before cellular respiration. This process generates a small amount of ATP and NADH, which are then used in the subsequent steps of cellular respiration to produce more ATP through the electron transport chain and oxidative phosphorylation in the mitochondria.

What is glycolysis and where does it take place?

Glycolysis is the metabolic pathway that breaks down glucose into pyruvate to produce energy in the form of ATP. It occurs in the cytoplasm of cells.

How many ATP molecules are produced in glycolysis?

In glycolysis, a total of two molecules of ATP are produced through substrate-level phosphorylation. However, four molecules of ATP are generated, but two are consumed during the process, resulting in a net gain of two ATP molecules.

What is the electron transport chain and where does it occur?

The electron transport chain is a series of protein complexes and molecules located in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors, generating ATP through oxidative phosphorylation. This process occurs during cellular respiration in eukaryotic cells, specifically in the mitochondria.

Which molecule combines with oxygen in the electron transport chain?

The molecule that combines with oxygen in the electron transport chain is hydrogen ions (H+). Oxygen acts as the final electron acceptor in the electron transport chain, combining with hydrogen ions and electrons to form water as a byproduct of cellular respiration.

What is the final electron acceptor in cellular respiration?

The final electron acceptor in cellular respiration is oxygen. Oxygen combines with electrons and protons to form water in the electron transport chain, allowing the generation of ATP in aerobic respiration.

Where is most of the ATP generated in cellular respiration?

Most of the ATP in cellular respiration is generated in the electron transport chain, which is located in the inner mitochondrial membrane. During this process, electrons are transferred through a series of protein complexes, ultimately creating a proton gradient that drives ATP synthesis through ATP synthase.

What waste product is produced during cellular respiration?

The waste product produced during cellular respiration is carbon dioxide (CO2).
