To answer the question about all reactions in respiration in plants, we need to understand that respiration in plants involves several steps and reactions. Here is a step-by-step explanation:

1. Glycolysis: The first step in respiration is glycolysis, which occurs in the cytoplasm of plant cells. In this process, glucose is broken down into two molecules of pyruvate. This reaction also produces a small amount of ATP and NADH.

2. Pyruvate Decarboxylation: The pyruvate molecules produced in glycolysis are transported into the mitochondria. Inside the mitochondria, each pyruvate molecule is converted into acetyl-CoA through a process called pyruvate decarboxylation. This reaction releases carbon dioxide and generates NADH.

3. Citric Acid Cycle (Krebs Cycle): Acetyl-CoA enters the citric acid cycle, also known as the Krebs cycle. This cycle takes place in the mitochondria and involves a series of reactions that further break down the acetyl-CoA. As a result, carbon dioxide is released, and NADH and FADH2 are produced. The cycle also generates a small amount of ATP.

4. Electron Transport Chain (ETC): The NADH and FADH2 molecules produced in the previous steps carry high-energy electrons. These electrons are transferred to the electron transport chain, which is located in the inner mitochondrial membrane. As the electrons move through the chain, their energy is used to pump protons (H+) across the membrane, creating a proton gradient. This gradient drives the synthesis of ATP through a process called oxidative phosphorylation.

5. ATP Synthesis: The proton gradient generated by the electron transport chain powers ATP synthesis. The protons flow back into the mitochondrial matrix through an enzyme called ATP synthase. This flow of protons drives the synthesis of ATP from ADP and inorganic phosphate.

Overall, these reactions in respiration in plants help convert glucose into ATP, which is the energy currency of the cell.
