the reactions occur in the matrix of the mitochondria
The first reactant and last product are the same.
Because of it's [cyclic] efficiency.
The first reactant and last product are the same.
The Krebs cycle is an example of an aerobic metabolic pathway, as it requires oxygen to function efficiently.
The Krebs cycle is primarily aerobic in nature, meaning it requires oxygen to function efficiently.
Reactions are considered part of a cycle when they occur in a recurring sequence, with the products of one reaction serving as the reactants for the next. This cyclic nature allows the reactions to continue in a continuous loop without the need for external sources of reactants. Examples include the Krebs cycle in cellular respiration and the Calvin cycle in photosynthesis.
The Krebs cycle is cyclic because it regenerates its starting molecule, oxaloacetate, after completing a series of reactions that generate high-energy molecules like NADH and FADH2. This enables the cycle to continue in a perpetual loop, facilitating the conversion of acetyl-CoA into ATP.

Hans Krebs discovered the Krebs cycle in the early 1930s while investigating how cells generate energy from carbohydrates and fats. He used a series of experiments involving the metabolism of animal tissues and identified a cyclic series of biochemical reactions that convert acetyl-CoA into carbon dioxide and energy in the form of ATP. This pathway, known as the citric acid cycle or Krebs cycle, is fundamental to cellular respiration and energy production in aerobic organisms. Krebs was awarded the Nobel Prize in Physiology or Medicine in 1953 for his groundbreaking work.
