The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid cycle, is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process.

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). This stage converts the NADH into ATP.

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Figure 17.3. Cellular Respiration. The citric acid cycle constitutes the first stage in cellular respiration, the removal of high-energy electrons from carbon fuels (left). These electrons reduce O2 to generate a proton gradient (middle), which is used to synthesize (more…)

Products and Functions of the Krebs Cycle For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.

The Krebs cycle is a part of cellular aerobic respiration. Complete answer: The Krebs cycle is also known as the citric acid cycle or TCA (tricarboxylic acid) cycle because the citric acid has 3- COOH groups and is the first product of the Krebs cycle.

The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation.

Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

This cellular respiration is carried out by every cell in both plants and animals and is essential for daily living. Cells use glucose and oxygen to produce yg p carbon dioxide, water, and energy. In cellular respiration, the carbohydrates from food are disassembled into glucose molecules. So do plants!

Because respiration releases energy it is chemically the reverse of photosynthesis, which uses energy from the Sun to make organic molecules. Photosynthesis and respiration are also connected ecologically because the vast majority of organisms use the oxygen produced by photosynthesis for respiration.

Cellular respiration is essentially the counterpart to photosynthesis, which uses sunlight as an energy source and provides Earth with oxygen. Without photosynthesis in plants, we would not have the oxygen needed for cellular respiration and could not provide our cells with the energy, or ATP, they need to live.
