Redox reactions
Redox reaction occur when there is a movement of electrons between atoms. Part of a redox reaction include:
Oxidising Agent: Atom losing/giving away electrons (causing reduction)
Reduction: Atom that gained/received the electron from the oxidizing agent, making it more negative and thereby the name reduction/reduced.
Reducing Agent: Atom that will be taking electrons …show more content…
Photosynthesis is the process by which plants capture sunlight - energy, and store it in the form of glucose molecules. When plants are eaten the glucose stores, unlike sunlight glucose can be broken down to ATP (at the end of cellular respiration) which is usable form of energy for our bodies.
Oxidizing Agent: Oxygen allows the cellular respiration reaction to take the Aerobic pathway, allowing the body to sustain functions in the long run. (Further explanation below)
Products:
Reduced: H2O, a products of cellular respiration is water. Water in different forms can be expelled from our bodies through breathing, sweat and urine.
Oxidized: CO2 is a second product, and will later be expelled from the body through exhalation. This CO2 is part of the natural cycle, and in smaller quantities than CO2 produced from car exhaust and industries.
Energy: 38 ATP - 40% and Heat -60% This is the main goal of cellular respiration.
Process of Cellular Respiration
Cellular respiration is a chemical process providing the body with usable and fast source of energy in the form of …show more content…
Glycolysis: Glyco- sugar, lysis- burst/break - the process in which a glucose molecule is split into two pyruvic acids (c-c-c). It is the first step of cellular respiration, it occurs in the cytosol of the cell and is anaerobic. Glycolysis requires 2 ATP, however the splitting of the glucose molecule produces 4 ATP therefore a positive net of 2 ATP.
Cellular respiration is an exothermic reaction, therefore following glycolysis enzymes and coenzymes will act as catalysts to assist continuing the reaction. Depending on whether or not enough oxygen is present, the reaction may proceed as anaerobic or aerobic.
Anaerobic: A fast process that does not require oxygen, and will continue in the cytoplasm of a cell, creating lactic acid. However anaerobic respiration is unsustainable, you would quickly run out of energy and pass out.
Aerobic: A slower process, that requires the presence of oxygen and will continue within the mitochondrial matrix. Aerobic respiration will produce energy in the form of 38 ATP (40%) and Heat
