During respiration (plants and animals) energy is released from sugar (glucose) by a series of chemical reactions. The sugar is broken down into carbon dioxide and water in a process which uses oxygen. Respiration is the chemical opposite of photosynthesis because it releases energy, using up food and oxygen and producing carbon dioxide. Photosynthesis requires engery (light) and produces food using up carbon dioxide and producing oxygen. Respiration is the release of energy from food. Breathing is the process of obtaining oxygen and removing carbon dioxide.

Short Answer: In cellular respiration Oxygen and Glucose, or C6H12O6, are broken down and used to produce ATP, adenosine triphosphate, CO2, and water. Long Answer: Glyco…lysis -> Kreb's Cycle -> Electron Transport Chain -> Chemiosmosis Glycolysis: Glucose + 2 ATP -> 2 Pyruvate + 4 ATP+2 NADH Glucose is ingested by the organism and brought into the cell through active transport. The Glucose molecule is phosphorylated, that is a phospate group is attached to both ends, and pulled apart. The phosphate group is then detatched from the split glucose and attached to ADP by an enzyme, forming ATP and Pyruvate. Kreb's Cycle: 2 Pyruvate+ 2 H2O -> 8 NADH + 2 FADH2 + 2 ATP + 4 CO2 Pyruvate is oxydized to form Acytl-CoA which is inserted into the Kreb's Cycle. This action produces 2 NADH molecules. When in the Kreb's Cycle, the Acytl-CoA is changed, removing 2 Carbon atoms in the form of CO2, and generating 1 ATP for each pyruvate that entered the cycle. Hydrogen atoms are removed during this cycle and attached to the electron carriers NAD and FAD for use in the Electron transport Chain. Electron Tranasport Chain and Chemiosmosis: 10 NADH + 2 FADH2 + 3 O2 -> 34 ATP + 6 H2O NADH and FADH2 are put through a series of enzymes where the Hydrogen atoms are removed to form an Electron Gradient. This gradient drives movement through a proton 'pump' that produces energy from the flow of the atoms. Each NADH that enters the ETC will produce 3 ATP molecules. Each FADH2 will produce 2 ATP. This answer is not exhaustive. For the full process, including all of the enzymes utilized, please talk to a biology professor or look into the purchase of a molecular biology text.
During Cellular Respiration , sugar is broken down to CO2 and H2O, and in the process, ATP is made that can then be used for cellular work. The overall reaction for cel…lular respiration: (does this reaction look familiar? Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different.). C6H12O6 + 6O2 -------------------> 6CO 2 + 6H2O + ~38 ATP.
Plants breathe as humans do. Carbon dioxide goes in the leaves and oxygen comes out.
by oxygen in the atmosphere

In photosynthesis, light energy is used in order to make organic food molecules for plants to eat. In cellular respiration, glucose is converted into energy (ATP) so the… human body can function properly.
Carbon dioxide is the product of respiration both plants and animals.
in the mictochondria
During Day time plants inhale Carbon-di-oxide and exhale Oxygen because they need it for photosynthesis while at night they inhale Oxygen and Exhale Carbon-di-oxide.
well what happens is the repiration is external
Plants also should respire every time. These are two separate biological processes
of course it does how do you think plants survive silly!
Respiration breaks down the sugar inside its cells.
Respiration is the chemical reaction that breaks down nutrient molecules (e.g glucose) in living organisms to release energy. When a plant respires it is opposite to when a hu…man respires. For a human oxygen is inhaled and carbon dioxide is exhaled. For plants carbon dioxide is inhaled and oxygen is exhaled. In plants respiration happens in the leaves because of diffusion (the movement of gas from an area of high concentration to an area of low concentration through a partially permeable membrane). CO2 and O2 constantly diffuse in and out of the plant as CO2 is necessary for the plant to photosynthesise. Hope this helped! Apologies if something is wrong or is I misunderstood your question...
