HELP ASAP!! DUE TOMORROW!! WILL MEDAL FIRST TO HELP!!

Lesson 1
--------
1. Which of the following are autotrophs?
Answer: b. plants

2. The principal chemical compound that living things use to store energy is
Answer: b. ATP

3. The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is
Answer: b. less

4. When a candle burns, energy is released in the form of
Answer: c. light and heat.

5. How do heterotrophs and autotrophs differ in the way they obtain energy?
Answer: Heterotrophs obtain their energy through the consumption of other organisms; autotrophs obtain their energy through sunlight, not consuming other organisms.

6. Describe the three parts of an ATP molecule.
Answer: Adenine, a purine base; ribose, a pentode sugar; and a phosphate.

7. Compare the amounts of energy stored by ATP and glucose. Which compound is used by the cell as an immediate source of energy?
Answer: Glucose can store 90x what ATP can, so glucose is the immediate source of energy.

8. Develop an analogy to explain ATP and energy transfer to a classmate who does not understand the concept.
Answer: ADP is like a ball at the bottom of the hill. Moving the ball to the top of the hill is like adding a phosphate group and making ATP. The ball now has the energy to roll downhill and move other objects in its path. ATP has energy to help change molecules.

9. Examine the photograph of the Indian pipe plant shown here. What can you conclude about the ability of the Indian pipe plant to make its own food? Explain your answer.
Answer: The Indian pipe plant has no chlorophyll or other pigment involved in photosynthesis, it probably cannot make its own food. Therefore, it must obtain food from other sources the way a heterotroph does. Perhaps it absorbs partly decayed food in the soil.
