Cellular Respiration Experimental Design Photosynthesis Enzymes! Grab Bag

Photosynthesis – 100 Where does photosynthesis take place? Chloroplast

Photosynthesis What process is unique only to plants? Photosynthesis

Photosynthesis What are the outputs of photosynthesis? O 2 and C 6 H 12 O 6 (sugar)

Photosynthesis What is the sources of energy in photosynthesis? Sunlight

Photosynthesis What is the name of the organelle and where is it located that a plant takes up carbon dioxide? Stomata – underside of leaf

Enzymes! 100 A substance that is acted upon in a biochemical reaction Substrate

Enzymes! Usually a protein, helps catalyze reactions. Enzyme

Enzymes! Name one condition that would affect enzyme rate (how fast it works). Temperature Concentration of substrate Presence of catalyst (enzyme)

Enzymes! What do enzymes do? Catalyze (speed up) reactions. Breaking stuff up or putting stuff together.

Enzymes! What is #3 pointing to? Active Site

Cellular Respiration – 100 What are the inputs of cellular respiration? O 2 and C 6 H 12 O 6 (sugar)

Cellular Respiration Where does cellular respiration occur in the cells? Mitochondria

Cellular Respiration What is energy in cellular respiration? Adenosine TriPhosphate (ATP)

Cellular Respiration Why do plants perform cellular respiration? Respiration converts a plant’s sugars into energy and releases the energy into the plant’s system. It is also responsible for producing and releasing water and carbon dioxide. Without cellular respiration, the plant would die.

Cellular Respiration Name this molecule: ATP (left) or ADP (right)

Experimental Design WHAT IS THE CONTROL? Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half the shower with coconut juice and the other half with water. After three days of “treatment” there is no change in the appearance of the green slime on either side of the shower. Side of the shower sprayed with water.

Experimental Design WHAT IS INDEPENDENT VARIABLE? Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half the shower with coconut juice and the other half with water. After three days of “treatment” there is no change in the appearance of the green slime on either side of the shower. Amount of coconut juice sprayed on half of shower.

Experimental Design WHAT IS THE RESULT/CONCLUSION? Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half the shower with coconut juice and the other half with water. After three days of “treatment” there is no change in the appearance of the green slime on either side of the shower. Coconut Juice does not affect shower slime. Homer should stop using it.

Experimental Design You want to see if you can affect how quickly amylase works on starch. Which is the enzyme? Amylase (helpful hint:enzymes typically end in – ase)

Experimental Design Untreated subjects used as test benchmark: in an experiment, the group of test subjects left untreated or unexposed to some procedure and then compared with treated subjects in order to validate the results of the test. Control group

Grab Bag Who wrote, The Lion, the Witch, and the Wardrobe? C.S. Lewis (one of Mrs. Hagens’ favorite authors)

Grab Bag What do scientists study when they look at lake sediment? Pollen (what kinds of plants lived in the past)

Grab Bag Name this molecule: Protein (Amino Acid)

Grab Bag What do leukemia sufferers have too many of? White blood cells (or leukocytes)
