  • Work in a living organism requires

    energy

  • example (1) of work done by transport substances across membranes

    active transport using the sodium-potassium pump in cell membranes

  • examples (2) of work done by transport substances across membranes

    exocytosis of digested bacteria from white blood cells

  • example (1) of work done by anabolic reactions

    synthesis of DNA from nucleotides

  • example (2) of work done by anabolic reactions

    synthesis of protein from amino acids

  • example (1) of work done by movement

    cellular movement of chromosomes via the spindle

  • example(2) of work done by movement

    mechanical contraction of muscles

  • example of work done by maintaining body temperature

    only occurs in mammals and birds

  • what is the primary source of energy

    the sun

  • which reactions store energy in organic matter

    photosynthesis

  • during photosynthesis which transform of energy occurs

    light energy into chemical energy

  • in photosynthesis, energy transform happens during this process

    synthesis of carbohydrates

  • carbohydrates formed in photosynthesis are used in what processes

    used in the synthesis of ATP

    OR

    combined & modified to form all the usable organic molecules that are essential for all metabolic processes in the plant

  • which organism carries out photosynthesis

    the first organism in a food chain

    plants

  • the purpose of respiration

    releases energy from the breakdown of organic molecules

  • what happens during the process of respiration in an organism

    transfer of chemical potential energy from nutrient molecules into a usable energy form that can be used for work

  • the glucose equation

    glucose + oxygen →  carbon dioxide + water + energy

    C6H1206 + 6 O2 →  6 CO2 + 6 H20 + 2870kJ

  • definition of autotrophs

    organism that are able to synthesise their own usable carbon compounds

  • the difference between heterotrophs and autotrophs

    heterotrophs require premade usable carbon compounds while autotrophs make their own usable carbon compounds through photosynthesis

  • energy can only be

    transformed from one form to another

  • great example of active transport

    sodium-potassium pump

  • in a potassium pumps, how many sodium and potassium ions are actively moved across the membrane respectively

    3 and 2

  • great example of an energy-requiring reaction

    the movement and contraction of muscles also requires substantial amounts of energy
