Photosynthesis and Respiration Notes:

Photosynthesis- coverts the ________________ into the energy of ______________ in_____________________.

• How was it discovered???• 17th century “How does a tree get bigger?”• _______________ thought - SOIL.• Joseph Priestly - ____________ experiment

General Photosynthesis Overveiw

___________1. 6_____+ 6 ______ ------------------> _______ +6 ____ __________2. Carried out in _______, _________, and some ___________.3. It is carried out in structures called ______________.4. The process is broken down into two parts: a). ______________ and b)._____________(Calvin Cycle).

How does Photosynthesis begin?THE LIGHT REACTION

• Specific light rays are absorbed by _________ (chlorophyll). ____________• Energy is trapped by transferring it to e- to carriers. _____________• ________________: Breaks water apart into ____ and _____• _____________: H+ ions pumped from ______ to _____ to produce energy, which

adds a P

• This set of reactions needs __________ and ____________.• They occur in the area of the chloroplast called the _______________.• Sunlight hits and activates an area called the ______________ causing water

molecules to split into _____ and ______.• The ___________ leaves the cell, while the H+ are used to help create _______.• These chemicals are sent to the _________ to be used in the _____________.

Where is energy stored? ___ ___ ___ molecule Adenine Ribose ______________

• _____________: able to use asource of energy to producefood directly. (They can maketheir own food)

• ________________:Obtainenergy from the food they eat.

CO2 + H2O

Sugars + O 2 Chloroplast

Light Energy

Photosynthesis Picture Overview: Label

Dark Reaction:• They occur in the ___________ of the chloroplast.• This process does not need __________ and can occur 24 hours a day.• In this reactions the plant uses _________to make a 3-carbon compound (______)

from carbon dioxide. 2 ________’s combine to make ____________.• This reaction is ________ and requires an enzyme named ___________. (most

abundant protein in the world)

Summary of Photosyntheis:• This is a building process• It requires _________, __________, ________, and ___________. It produces

_________and ____________.• The ______________ produces oxygen and the needed materials for the

__________________.• The Dark reactions produce ___________ from the carbon dioxide and ATP.• __________ will be used to produce ___________ and other materials.

Cellular Respiration: ________________ is one of the main sources of energy for all living things. 1 gram of ___________ releases _____________of energy(heat) when burned A ____________ is the amount of energy needed to raise ____ gram of water, by

___ degree ___________. If the cell were to release all of this energy at once, the heat released would kill it.

(So a little at a time) This process is called _________________.

Overview of Respiration: Label the diagram

1st step is ________________: Glycolysis means _______________. It occurs in the ____________ of the cell. It takes the __________________ and divides it into two 3 carbon compounds

called __________________. It does not require ___________ to complete this process. This is also called

________________ respiration. Overall it produces _________ molecules

Fill in the steps:

What if NO oxygen is present? ________________________

___________ Acid Fermentation Accumulated __________acid turns to __________ acid if NO oxygen is present. Muscle cells run out of stored oxygen, so to produce energy they make ________

________, which build up in muscles to cause _____________.

____________ Fermentation

When _________ and other ______________ run out of ___________, theyconvert pyruvic acid into __________ (C2H6O) and CO2.

_________________ evaporates off in baking.

What if Oxygen IS present? ________________________ This ______________ occurs in the center of the ______________ called the

__________. Pyruvic acid will lose a ______ and become ________________ The _________________ will combine with acetic acid to form citric acid,

beginning the cycle. There are nine reactions the molecule will undergo. All reaction are helping to produce more _________.

Flowchart for Cellular Respiration:

Electron Transport Chain: All of the molecules produced are taken to the inner _____________________

where they are used to produce ______. The _____________________ is used again to help convert ADP into ATP. ___________ is the final electron acceptor in electron transport system and

combines with _______ to make_____________.

Overall TOTAL production of cellular respiration: Glycolysis = __________ Krebs Cycle (including electron transport chain) = _________

Total = ________ per 1 glucose
