400

#1: AUTOTROPH: Organism that can make food from CO2 and an energy source like the sun. #2: Ex: Plants, algae, some bacteria #1: HETEROTROPH: Organism that can't make their own food. #2: Ex: Animals, fungi

2 QUESTIONS! 1. Define these terms: AUTOTROPH and HETEROTROPH. 2. Give an example of each term.

500

#1: See assignment #1 #2: Phosphate bonds break, and this releases energy

2 QUESTIONS! 1. What is the ATP-ADP cycle? Draw and label the cycle. 2. How is energy released from an ATP?

I'm feeling lucky

Ribose

What is the name of the 5-carbon molecule that is part of an ATP molecule?

200

ADP and ATP keep forming and re-forming depending on the needs of the cell.

What is the reason why the ATP-ADP cycle is called a cycle? Explain your answer.

300

#1: 3 phosphate groups, ribose, adenine (see assignment #1) 2: Adenosine

2 QUESTIONS! 1. Draw and label all the parts of an ATP molecule. 2. What does ribose + adenine equal?

Cytoplasm

Where in the cell does glycolysis take place?

300

What is the number of ATP's needed to prepare a glucose molecule to break (split up)?

400

#1: "Splitting sugars." Glucose is split in half to form 2 pyruvate molecules #2: 2 NADH

2 QUESTIONS! 1. What does the term glycolysis refer to? 2. How many NADH (electron carriers) are made during glycolysis?

500

4 ATP molecules

What is number of ATP molecules produced during glycolysis?

Krebs Cycle

The mitochondria

What is the name of the structure where the Krebs Cycle takes place?

200

Acetyl-Coenzyme A (Acetyl-CoA)

What is the name of the molecule that is formed when 2 carbons from pyruvate combine with Coenzyme A?

300

#1: CO2, ATP, NADH, FADH2 #2: The Citric Acid Cycle

2 QUESTIONS! 1. The Krebs Cycle is a set of reactions that breaks down Acetyl-CoA. What are the 4 things that are formed from this cycle? 2. What's another name for the Krebs Cycle?

400

#1: 4 CO2 molecules #2: A 2-carbon molecule and a 4-carbon molecule

Organic molecules (like glucose) and O2 (oxygen)

What are the raw materials needed for cellular respiration?

200

Glycolysis, Krebs Cycle, Electron Transport Chain

What are the 3 stages/phases of cellular respiration in the correct order?

300

LIGHT (energy) + CO2 + H2O --> C6H12O6 + O2

What is the chemical equation for photosynthesis?

400

#1: Cellular Respiration #2: C6H12O6 + O2 --> Usable energy (ATP) + CO2 + H2O
