photosynthesis
The reaction you're describing is combustion. In the presence of oxygen, organic compounds (such as hydrocarbons) undergo combustion to produce carbon dioxide, water, and energy in the form of heat and light. This reaction is exothermic, meaning it releases energy.
Oxygen and glucose undergo a process called cellular respiration, where glucose is broken down in the presence of oxygen to produce energy, carbon dioxide, and water. This reaction releases ATP, which provides energy for the cell to carry out its functions.
carbon dioxide is a product of aerobic respiration that all cells of all plants and animals undergo to produce energy. (except the anerobes such as yeast that give off ethanol and carbon dioxide instead, using a very different reaction that also gives off energy). they don't do so when they eat, but they create this waste product when releasing food energy into cellular energy.
No, animals do not have the ability to undergo photosynthesis. Photosynthesis is a process that only plants, algae, and some bacteria can perform, using sunlight to convert carbon dioxide and water into energy. Animals obtain energy by consuming plants or other animals.
we can use it in the reaction of producing energy
Energy is harvested to produce ATP from the process of cellular respiration.
Yes, uranium is the most important nuclear fuel now.
Oxygen is the reactant needed for cellular respiration that is absent from the fermentation reaction. In the absence of oxygen, some organisms, like yeast, undergo fermentation to produce energy in the form of ATP.
by reducing the activation energy required to initiate the reaction
activation energy
The spark of energy is needed to initiate the combustion process by breaking the bonds within the fossil fuel molecules, creating reactive intermediates that can undergo further reactions with oxygen to produce heat and light energy. This initial energy input is required to overcome the activation energy barrier and start the combustion reaction.
Methane does not require oxygen to produce energy, as it can undergo anaerobic metabolism in some microorganisms to generate ATP.
