  2. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    Since energy is released when ATP is broken down, energy is required to rebuild or resynthesize it. The building blocks of ATP synthesis are the by-products of its breakdown; adenosine diphosphate (ADP) and inorganic phosphate (P i). The energy for ATP resynthesis comes from three different series of chemical reactions that take place within ...

  3. OpenCards - Wikipedia

    en.wikipedia.org/wiki/OpenCards

    OpenCards uses PowerPoint ppt-files as flashcard sets. Thereby, slide-titles are considered as questions and the slide contents as their answers. OpenCards also supports a reversed mode in which slide contents are treated as questions and the slide title as their answers, which allows creating image, formula or sound questions.

    Primary energy, energy contained in raw fuels and any other forms of energy received by a system as input to the system. Radiant energy, energy that is transported by waves; Rotational energy, part of an object's total kinetic energy due to its rotation; Solar radiation, radiant energy emitted by the sun, particularly electromagnetic energy

  5. Carbohydrate catabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_catabolism

    The energy from the acetyl group, in the form of electrons, is used to reduce NAD+ and FAD to NADH and FADH 2, respectively. NADH and FADH 2 contain the stored energy harnessed from the initial glucose molecule and is used in the electron transport chain where the bulk of the ATP is produced.

  6. Protein catabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_catabolism

    Oxidative deamination is the first step to breaking down the amino acids so that they can be converted to sugars. The process begins by removing the amino group of the amino acids. The amino group becomes ammonium as it is lost and later undergoes the urea cycle to become urea, in the liver. It is then released into the blood stream, where it ...

    Photosynthesis is a complex energy transformation process in which sunlight, carbon dioxide and water are converted to chemical energy by living organisms. More selected pictures Picture 17

  8. Bond cleavage - Wikipedia

    en.wikipedia.org/wiki/Bond_cleavage

    The bond-dissociation energy of a bond is the amount of energy required to cleave the bond homolytically. This enthalpy change is one measure of bond strength . The triplet excitation energy of a sigma bond is the energy required for homolytic dissociation, but the actual excitation energy may be higher than the bond-dissociation energy due to ...

  9. Comminution - Wikipedia

    en.wikipedia.org/wiki/Comminution

    The comminution of solid materials consumes energy, which is being used to break up the solid into smaller pieces. The comminution energy can be estimated by: Rittinger's law , which assumes that the energy consumed is proportional to the newly generated surface area; [ 4 ]
