Compare contrast photosynthesis cellular respiration essay

Carbon dioxide is reduced to form two 3-carbon sugar phosphate molecules which turns into our glucose at the end of photosynthesis. Photosynthesis is a two part process which includes photophosphorylation light reactions and carbon fixation dark reactions.

Cellular respiration takes place in the mitochondria of cells. Therefore, cellular respiration and photosynthesis are similar yet different in many ways. Get Full Essay Get access to this section to get all help you need with your essay and educational issues. Without it, life on Earth would cease to exist.

They are also necessary to the energy exchange that living things need to survive. Even though cellular respiration and photosynthesis are related in a few ways such as they both use energy transformation, processes occur in double membraned organelles, and both processes use chemiosmosis.

Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy. Although both processes are found in double membraned organelles, photosynthesis occurs in chloroplasts in plant cells and cellular respiration occurs in the mitochondria of animal cells.

Photosynthesis uses water and carbon dioxide as reactants to produce glucose and oxygen where as cellular respiration uses glucose and molecular oxygen as reactants to produce water, carbon dioxide, and energy ATP.

It does not require the presence of sunlight and is always occurring in living organisms. Cellular respiration Photosynthesis vs.

Cellular Photosynthesis and Respiration Essay Sample

More essays like this: Cellular respiration is the metabolic process in which food is broken down to form stored energy in the form of ATP. Photosythesis is the process in which light energy is converted into chemical energy to produce glucose. Photosynthesis takes place in the chloroplasts of cells.

They are also different in the fact that photosynthesis creates glucose and releases oxygen into the atmosphere while cellular respiration creates energy and releases carbon dioxide and water into the atmosphere.

Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose. Electrons transferred through the ETC create a concentration gradient. Plants perform both photosynthesis and respiration, while animals can only perform respiration.

While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. This process is what gives energy to all living organisms either directly or indirectly. They both consume and create the same substances water, glucose, oxygen, and carbon dioxide but in different ways.

Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need. During glycolysis a net gain of 2 ATP is formed.

Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy. In glycolysis glucose is broken down in a ten step process into 2 3-carbon pyruvate molecules. The next process is called the carbon fixation.

Cellular respiration Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.Comparison & Contrast between Photosynthesis and Cellular Respiration Essay by Gidz, High School, 11th grade, A+, November download word file, 4 pages download word file, 4 pages 0 votes.

Definitions of photosynthesis and respiration. Photosynthesis is a process in photoautotrophs that converts carbon dioxide into organic compounds in the presence of sunlight.

Photosynthesis vs. Cellular respiration

Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste. In contrast, The site of photosynthesis is chloroplast, while the sites of cellular respiration are cytoplasm and mitochondrion.

The chloroplast, which has two membranes around a central aqueous space, is found mainly in mesophyll cells forming the tissues in the interior of the leaf. Cellular respiration and photosynthesis are critical in the continued cycle of energy to sustain life as we define it.

Both have several stages in which the creation of energy occurs, and have varied relationships with organelles located within the eukaryotic cell. The processes are the key in how. Cellular Photosynthesis and Respiration; Cellular Photosynthesis and Respiration Essay Sample.

Photosythesis and Cellular Respiration are both processes in Biology which transform energy in one form to another. Photosythesis is the process in which light energy is converted into chemical energy to produce glucose. Contrast and compare.
