Cellular Respiration Equation

Notice Anything?The photosynthesis equation is the cellular respiration equation, but backwards. Photosynthesis makes the sugar. Through cellular respiration, we turn in into energy. All living things contain a form of glucose also known as sweet sugar. Glu means sweet Cose means sugarLight Light is important. Very important. Light is a form of electromagnetic energy. Green light is reflected. Red and blue are mainly absorbed. Primary colors are green, red, and blue. NOT yellow, magenta (red), and cyan (blue).

Chloroplast and Chlorophyll Chloroplast has an important role. It has chlorophyll that captures the suns rays.Inside chloroplasts are thylakoids that are disc-like. They trap the suns rays. Chlorophyll is a chemical found inside the chloroplast giving its green pigment.

Process of Photosynthesis It doesnt happen overnight. There are 2 main steps.First- light dependent reaction (Calvin cycle) It turns light into ATP Second- light independent reaction it doesnt necessarily mean that it happens at night. It happens when ATP is turned into glucose.

7Cellular Respiration How living organisms turn glucose into energy There are byproducts like water and carbon dioxide. Carbon dioxide is a waste. CO2 mixes with water helping maintaining the bloods pH (around 7.5). Too much carbon dioxide causes to pH to lower, so CO2 has to leave on a continuous process.FootnotesGlucose: A simple, 6 carbon sugar that serves as the primary energy source ATP(Adenosine triphosphate): The major energy currency of the cell. NADH and FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

Stages of Cellular Respiration GlycolysisFermentation (ONLY FOR ANAEROBIC CELLULAR RESPIRATION) Krebs's Cycle A.K.A. Citric Acid Cycle Electron Transport ChainGlycolysisThe first stage is glycolysis in aerobic and anaerobic cellular respiration. An easy way to think about it is splitting sugars. It occurs in the cytoplasm. It breaks glucose down to two pyruvic acid or pyruvate. This stage doesnt require oxygen. This stage requires 2 ATP and produces 4 ATP.FermentationAerobic? Anaerobic?Fermentation takes NADH to produce NAD+. This stage makes nothing, no energy or ATP.

Krebs's Cycle A.K.A. Citric Acid CycleThis step uses the pyruvic made in the glycolysis stage.It produces ATP and several molecules of NADH AND FADH2. This stage produces 2 ATP.

Electron Transport ChainThe chain is made using FADH2 AND NADH (made in the previous cycles). The electron transport chain makes a proton gradient that makes the production of 34 ATP. It takes place in the mitochondria matrix.

ReviewBy the way, Cellular Respiration produces a total of 38 ATP.
