Overview of Cellular Respiration Chapter 4

In the last chapter green plants used ________________ to AUTOTROPHS ___________ use energy from sunlight or chemicals to make their own food. In the last chapter green plants used ________________ to trap energy from __________ and make ______________. PHOTOSYNTHESIS sunlight food (glucose)

in a process called _______________ broken down energy ATP In this chapter, we will learn how this glucose is ____________ by organisms and the _______ is stored as _______ in a process called _______________ broken down energy ATP CELLULAR RESPIRATION

ATP cellular respiration Aerobic respiration ________________ This process that releases energy (_____) by breaking down food molecules in the presence of oxygen is called ________________ Or it is called _______________________because it uses oxygen. cellular respiration Aerobic respiration

Cells require a ______________________for life processes but keep only a _____________of _____________ on hand. Cells can regenerate ATP as needed by using the _____________________________ like glucose. The energy stored in glucose by photosynthesis is released by _______________________and repackaged into the energy of ATP. constant source of energy small amount ATP energy stored in foods cellular respiration

ALL LIVING THINGS NEED ENERGY! What kind of organisms do this? plants fungi bacteria ________ (Including _______) animals ______ ______ ______ humans ALL LIVING THINGS NEED ENERGY!

How do we get the sugar from the plants? REMEMBER! HETEROTROPHS _______________ get their energy by eating other organisms. We get the energy the plants stored as glucose by _____________ directly or eating the _________ that ate the plants. eating plants animals

slowly many steps light and heat in ________________. CELLULAR RESPIRATION happens __________ in ________________. If all the energy was released in one step… most would be lost as ____________________! slowly many steps light and heat  

Cellular Respiration: (Two kinds—Aerobic and Anaerobic) Cellular respiration is the process by which the energy of ___________ is ____________ in the cell to be used for life processes (movement, breathing, blood circulation, etc…) Aerobic = ______________ Anaerobic = _______________ glucose released With oxygen Without oxygen

Respiration occurs in _______________and can take place either _________________________present. all cells with or without oxygen

MITOCHONDRIA = cell power plant Surrounded by ___________ membrane Outer membrane & Inner membrane (called _______________ ) Space between inner membrane & outer membrane = ____________________ Space inside cristae folds = _________________ CYTOPLASM surrounds mitochondria DOUBLE CRISTAE INTERMEMBRANE SPACE MATRIX

The two equations are exact opposites! PHOTOSYNTHESIS ___________ + _________ + ___________ →_______________ + __________ 6 CO2 6 H2O C6H12O6 6O2 CELLULAR RESPIRATION C6H12O6 6 CO2 _____________ + _________ →________ + __________ + __________ ______________________________________________________________ 6O2 6 H2O The two equations are exact opposites!

Aerobic Respiration: _________________ Occurs in the _________________ of the cell Total of ___________molecules produced General formula for aerobic respiration: requires oxygen mitochondria 36 C6H12O6 + 6O2 6 CO2 + 6H2O + 36 ATP glucose + oxygen carbon dioxide + water + energy Human cells contain a specialized structure – the mitochondrion – that generates energy.

Summary: 3 steps: 1st Glycolysis 2nd Krebs cycle 3rd Electron Transport Chain (ETC)

_____________________ GLYCOLYSIS Happens in ______________ KREBS CYCLE happens in ________________ ELECTRON TRANSPORT Enzymes found in _____________________ CYTOPLASM outside mitochondria MATRIX inside mitochondria cristae inner membrane of mitochondria

Anaerobic Respiration: occurs when _______________ is available to the cell (2 kinds: Alcoholic and Lactic Acid) Also called _________________ ______________________ than in aerobic respiration no oxygen fermentation Much less ATP produced

Alcoholic yeast bacteria baking brewing gas rise ____________________ fermentation—occurs in _____________ and _____________ Process used in the ______________and _____________ industry—yeast produces CO2 ___________ during fermentation to make dough ___________and give bread its holes bacteria yeast baking brewing gas rise glucose ethyl alcohol + carbon dioxide + 2 ATP

Lactic Acid muscle cells exercise oxygen cannot tissues ______________fermentation—occurs in ____________________. Lactic acid is produced in the muscles during rapid ________________ when the body ________________supply enough ________________ to the _____________—causes burning sensation in muscles muscle cells exercise cannot oxygen tissues glucose lactic acid + carbon dioxide + 2 ATP
