  • Cellular Respiration and Photosynthesis

  • _____________ processes are the chemical processes that occur in all living things. Two of these processes are _____________ _____________ and _____________. They are both controlled by _____________. _____________ ______________ is carried out by _____________ organisms. ______________ is carried out by _____________ _____________ and some single-celled organisms.

  • II. Cellular Respiration: You learned that when you eat foods that are

    carbohydrates (bread and pasta) they are broken down by your ____________ ______________.

    They are broken down into ____________ ____________ (glucose)

    The bonds of glucose are then broken by a series of ____________ ______________ _____________ to form energy.

    This energy is captured into the bonds of the High Energy Molecule known as ____________ (Adenosine Triphosphate)

    This energy is used by the organism for its ______________ ______________

    digestive system

    simple sugars

    Enzyme controlled reactions

    ATP

    Life Activities

  • Diagram of ATP

    II A. The ATP/ADP Cycle: ATP and ADP are compounds that are found in all cells. The D in ADT is for Diphosphate or ________ phosphates. The T in ATP is for Triphosphates or ________ phosphates. ADP and ATP are converted back and forth as a ____________ is added or removed.

    2

    3

    Phosphate (P)

  • We get energy to put the third phosphate on to ADP by burning _____________. The most common food that is burned is ____________.

    Food Glucose

  • ATP 100% Renewable Energy

    All living things rely on one source of energy to do all things from building molecules to flexing muscles = ATP (Adenosine Triphosphate). Breaking down ATP releases energy and cells constantly replace their ATP by attaching a spare phosphate onto ADP. The energy from that comes from food we eat (animals) or make (plants). Enzymes control the breaking and making of ATP

  • II. B Two Types of Respiration: There are two ways to burn glucose (two types of

    respiration) Anaerobic Respiration does NOT use

    ____________. This is also called ____________.

    Aerobic Respiration USES _____________ II. C Anaerobic Respiration (fermentation) Some cells lack the _____________ necessary

    for aerobic respiration and other cells like your muscle cells change to anaerobic respiration when oxygen is lacking

    Oxygen Fermentation

    Oxygen

    Enzymes

  • The enzymes necessary for this type of respiration are located in the ____________ of the cells. In Anaerobic respiration ____________ is partially broken down by the ____________ to form either ____________ ____________ or ____________ _____________ and _____________. Both of these form only ______________ ATP molecules. ____________ and ___________ ___________ cells form the lactic acid and 2 ATP. ____________ form the alcohol and carbon dioxide and 2 ATP.
