Respiration and photosynthesis are reactions that take place in the environment which complement each other, in the other case can be seen as a same reaction but happening in reverse of each other (Tang, 2005). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Respiration to take place requires glucose and oxygen to yield carbon dioxide and water. Since the product of photosynthesis are used as requirements for respiration as well product of respiration are used as requirement for photosynthesis to take place this is why we call them complement reaction where each reaction depends on one another. Thus respiration and photosynthesis leads to a formation of a critical cycle of energy and matter that supports the continued existence of life on earth (Kromer, 1995). Cellular respiration and photosynthesis are the two main processes out of the majority of living organisms to gain energy from the operational nature. Whereas the photosynthesis performed by most plants can make their own food, most of the animals to meet their …show more content…
Glycolysis occurs in the cytoplasm of the cytoplasm. Glycolysis is mainly cleavage of glucose and occurs in the presence of an enzyme, in which glucose is broken down into two molecules of pyruvate also known as pyruvic acid. This is the distribution of glucose occurred ATP molecules formed passes to the next stage of respiration. The energy used to break the sugar molecules is provided by two molecules of ATP. Since glycolysis proceeds more energy is released and the energy used to make four ATP molecules. From the above statement you can see that photosynthesis contributes only two molecules of ATP used in glycolysis, but the process gives four molecules of energy, showing a net gain of two ATP
