Glycolysis evolved first. Cells of all types of organisms are able to carry out glycolysis. The Krebs cycle arose after photosynthetic organisms began adding oxygen to the atmosphere because Krebs cycle requires oxygen and glycolysis does not.
The reactants for the Krebs cycle come from the breakdown of carbohydrates, fats, and proteins into acetyl-CoA, which is then used as the starting molecule for the cycle. These molecules are broken down by various metabolic pathways in the cell to produce the necessary substrates for the Krebs cycle.
CO2 is produced during the Krebs cycle as a byproduct of decarboxylation reactions that occur when citrate is converted to isocitrate, isocitrate to alpha-ketoglutarate, and alpha-ketoglutarate to succinyl-CoA. These decarboxylation reactions release carbon dioxide as a waste product.
One ATP is formed, along with three NADH, and two CO2. (? re:numbers) A number of different molecules are involved during the Kreb's [citric acid] Cycle, but those are the products that come out of the cycle. (Good).
In the Krebs cycle, also known as the citric acid cycle, carbon dioxide (CO2) is produced during the decarboxylation reactions that occur at specific steps in the cycle. Specifically, CO2 is released when isocitrate is converted to alpha-ketoglutarate and when alpha-ketoglutarate is converted to succinyl-CoA. These steps involve the removal of carbon atoms from the organic molecules, resulting in the release of CO2 as a byproduct. This process is essential for cellular respiration, as it helps to oxidize substrates to generate energy.
The electrons moving along the inner membrane of the mitochondria come from molecules such as NADH and FADH2, which are generated during the citric acid cycle and glycolysis. These molecules donate their electrons to the electron transport chain to drive the production of ATP through oxidative phosphorylation.
If by "first carbon" you mean the first CO2 released in the cycle then the answer is, from OAA. NOT from acetyl CoA.

Yes, the electron transport chain can occur without the Krebs cycle. The electron transport chain generates ATP by transferring electrons through a series of protein complexes in the inner mitochondrial membrane, regardless of whether the electrons come from the Krebs cycle or other sources.

Aerobic and anaerobic pathways. instant energy comes from anaerobic pathways (Glycolysis) and long durations come from aerobic pathways (Krebs cycle).
After glycolysis you will go through bridging reaction to the Krebs cycle, also known as the citric acid cycle because of the use of citric acid. the reducing power generated indirectly helps to power oxidative phosphorylation that occurs, which yields a total of 34 ATP's from one glucose molecule. Good luck

this is reaction done by micro organisms in this oxidation reaction taking place between oxygen and carbohydrate/ fat/ proteins. from this main product is energy gain by micro organisms and by product CO2 and water given out . this CO2 and water taken by plant to from carbohydrate/ fat/ protein. such a way this cycle take place.
The heat that is generated by the body comes from the food you eat. The oxidation of pyruvic acid (from glucose) into CO2, water and energy is called Krebs cycle. This cycle occurs only in the presence of oxygen. Hence it is an aerobic process. It takes place in the mitochondria.
