Most of these deal with carbon in the form of CO2 7. Read more about the ocean and the carbon cycle here. There are six main processes in the carbon cycle: photosynthesis, respiration, exchange, sedimentation, extraction, and combustion. W, X, Y and Z are carbon compounds. It's important to remember that phytoplankton also use CO2 for photosynthesis and store carbon and that the processes of decomposition and carbon storage also occur in the ocean. Click here to get an answer to your question The given diagram shows some stages in the carbon cycle. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. The Carbon cycle implies the exchange of Carbon between the various organic and inorganic elements in the atmosphere and the biosphere. In stage 2, the organic molecule is reduced using electrons supplied by NADPH. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule, 3-PGA. The total amount of carbon in the ocean is about 50 times greater than the amount in the atmosphere, and is exchanged with the atmosphere on a time-scale of several hundred years. Figure: The Calvin Cycle: The Calvin cycle has three stages. Gas exchange between the ocean and the atmosphere is always occurring, but overall the ocean stores CO2. The ocean plays a vital dominant role in the Earths carbon cycle. Krebs cycle was named after Hans Krebs, who postulated the detailed cycle.

The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs. The Krebs cycle or Citric acid cycle is a series of enzyme-catalyzed reactions occurring in the mitochondrial matrix, where acetyl-CoA is oxidized to form carbon dioxide and coenzymes are reduced, which generate ATP in the electron transport chain. Carbon ends up in the ground when plants and other organic matter decays and is buried for very, very long periods of time. About Transcript Cellular respiration is the process by which cells derive energy from glucose. Humans use fossil fuels in the ground (oil, gas, coal) and when these fuels are burned, they emit CO2, releasing more carbon into the atmosphere. A simple carbon cycle without interference from human activity includes the following stages: plants and animals emit CO2 during respiration, photosynthetic plants use CO2 in photosynthesis, organisms give off CO2 when they decompose, and carbon is stored fossil fuels and sediments for long periods of time before processes such as erosion and
