MISSION COUNTDOWN Write this down (on agenda, alarm on phone…whatever will get you to remember!) Homework will be posted online this afternoon (test review). Must be completed by Monday BEFORE class as you have a TEST ON MONDAY Finish your leaf foldable – grab a laptop and begin RIGHT AWAY Timed

Quick review of photosynthesis

Photosynthesis: Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose

Photosynthesis occurs in the chloroplasts of plants

Chlorophyll is the pigment inside the chloroplast the absorbs light for photosynthesis As the chlorophyll in leaves decays in the autumn, the green color fades and is replaced by the oranges and reds of carotenoids.

General formula for photosynthesis: carbon dioxide + water + light glucose + oxygen CO2 + H2O + light C6H12O6 + O2

Summary: Light Dependent Reaction—H2O is broken down and light energy is stored Light Independent—energy in ATP makes glucose

Notes – Title you next available page: CELLULAR RESPIRATION

What kind of organisms do this? In this chapter, we will learn how this glucose is ____________ by organisms and the _______ is stored as _______ in a process called ___________________ broken down energy HIGHLIGHT THIS WORD! ATP CELLULAR RESPIRATION What kind of organisms do this?

What Does ATP Do for You? It supplies YOU with ENERGY!

Cells usable source of energy is called ATP Cell Energy: Cells usable source of energy is called ATP ATP stands for adenosine triphosphate Highlight this word! Adenine Ribose 3 Phosphate groups

How Do We Get Energy From ATP? By breaking the high- energy bonds between the last two phosphates in ATP

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

Highlight “Mitochondria” Image from: http://vilenski.org/science/safari/cellstructure/cytoplasm.html Part of cell that Stores ATP(energy) is = _______________ mitochondria Highlight “Mitochondria” http://www.clickatutor.com/mitochondria.jpg

Cellular Respiration: Cellular respiration is the process by which the energy of glucose is released in the cell to be used for life processes (movement, breathing, blood circulation, etc…)

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

Respiration occurs in ALL cells & happens with or without oxygen.

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

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

Lactic acid fermentation—occurs in muscle cells Lactic acid produced during intense exercise when not enough oxygen( causes muscle ache)
