Where does energy come from? What are some ways organisms use energy? Are there different types of energy?
ATP- adenosine triphosphate Is made up of: Adenosine Ribose Phosphate group
Storing Energy ADP- adenosine diphosphate Only has 2 phosphate groups When a cell has energy to store, it can store small amounts of it by adding a phosphate group to ADP
Releasing Energy ATP- has 3 phosphate groups When a cell requires energy, a cell can add or subtract phosphate groups
How Do We Get Energy From ATP? By breaking the high- energy bonds between the last two phosphates in ATP
How does that happen? ATP-ase catalyzes the decomposition of ATP from ADP ATPsynthase does the opposite and catalyzes the production of ATP from ADP

What can cell use this energy for? 1.Active transport 2.Cell movement 3.Making proteins Any thing else????
Facts: Cells use glucose to store energy 1 glucose molecule stores 90x the energy of 1 molecule of ATP
Let’s get started! 1.Grab a textbook 2. Turn to Quick lab on page 198 (What is the waste product produced by photosynthesis) 3. Read the procedure and with a partner make a prediction about what you will observe from the plant using the information from the web quest. 4. Do I have a volunteer???
Do Now Answer the following questions: 1. In addition to light and chlorophyll, photosynthesis requires a. water and oxygen b. water and sugars c. oxygen and carbon dioxide d. water and carbon dioxide 2. Write the basic equation for photosynthesis using the molecular formulas and the names of the starting and final substances of the process.
1.Give an example of an autotroph and heterotroph in this picture. 2.How is photosynthesis important to these organisms?
What is photosynthesis? Process ___ use to make their own food. Which category do plants fall under. Autotroph or heterotroph? Plants, bacteria algae
a._______ : organisms, like plants, that use light energy from the sun to produce their own food Because plants can “manufacture” their own energy directly, they are self-sufficient. b.____________: organisms that obtain energy from foods they consume All other forms of life, such as humans, animals, insects and even bacteria, depend on other living things for food. Autotrophs Heterotrophs
Plant leaves contain _____________ (green color) makes photosynthesis possible, it captures the sunlight. What organelle in a plant can you find___________? Chlorophyll Chloroplast
Leaf Anatomy- where are chloroplasts located?
What is in the chloroplast that captures light?
What does a plant need to perform photosynthesis? The ______ is combined with ______, _______ and nutrients from the soil. o CO 2 water sunlight CO2
O2O2 plant glucose oxygen
What is the equation for photosynthesis? sunlight Carbon dioxide + Water → Glucose + Oxygen ReactantsProducts
Plants and animals need each other to survive. Why?
Animals including humans make the __________plants need. They (the plants) make the __________and food we need CO 2 ( ) O2 ( )
2 Parts to Photosynthesis Light dependent reaction: requires light for process to proceed Light independent reaction: (Calvin cycle) does not require light M
Chloroplast Light O2O2 Sugars- Glucose CO 2 Light- Dependent Reactions Calvin Cycle NADPH ATP ADP + P NADP + Chloroplast Photosynthesis: An Overview Go to Section: water
PHOTOSYNTHESIS What affects photosynthesis? –Light intensity: as light increases, rate of photosynthesis increases
PHOTOSYNTHESIS What affects photosynthesis? –Carbon Dioxide: As CO 2 increases, rate of photosynthesis increases
PHOTOSYNTHESIS What affects photosynthesis? –Temperature: Temperature Low = Rate of photosynthesis low Temperature Increases = Rate of photosynthesis increases If temperature too hot, rate drops ?v=gvPYfe7P_ts
Evaluate the quick lab With your partner answer the 3 questions in the textbook. Use the information, observations collected in class to answer them.
