Difference between Respiration and Photosynthesis | …

Photosynthesis and cellular respiration are similar in that they both undergo chemiosmosis.

Difference between Respiration and Photosynthesis

In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.

aerobic and anaerobic respiration ..

Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules.

Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.

Theprocesses of photosynthesis and respiration take in and release the gasses CO2and O2.Duringphotosynthesis, cells take in release .During respiration, cells take in and release


Cellular Respiration and Photosynthesis

Glycolysis itself yields two ATP molecules, so it is the first step of anaerobic respiration. , the product of glycolysis, can be used in to produce ethanol and + or for the production of lactate and NAD+. The production of NAD+ is crucial because glycolysis requires it and would cease when its supply was exhausted, resulting in cell death. A general sketch of the anaerobic steps is shown below. It follows Karp's organization.

The main function of photosynthesis is to produce food and capture energy.
Photosynthesis is divided into two stages: the Light Dependent Reaction and the Light Independent reaction which is also referred to as the Calvin Cycle.
What is Cellular Respiration?
Cellular respiration is a series of redox reactions as well as other reactions in order to create energy in the form of ATP.

Energy Transformation: Photosynthesis vs. Cellular Respiration

Aerobic respiration, or in the presence of oxygen, uses the end product of (pyruvate) in the to produce much more energy currency in the form of than can be obtained from any . Aerobic respiration is characteristic of when they have sufficient oxygen and most of it takes place in the .

BBC - GCSE Bitesize: Photosynthesis and respiration


The main function of cellular respiration is to break down food and release energy.
There are two types of cellular respiration: aerobic and anaerobic.
Referring back to the introduction, cellular respiration and photosynthesis go through different stages each involving different reactions.
Photosynthesis:
Divided into two stages
: Light dependent reaction and Light Independent reaction/Calvin cycle

Photosynthesis Versus Cellular Respiration :: Biology

Students will learn about chloroplasts by the construction
and labeling of a chloroplast; aerobic respiration in the mitochondria by the
construction and labeling of a mitochondrion; and the chemical interaction of
ADP and ATP by atomic modeling of ADP and ATP molecules as well as a game.
