Question

1. where are these high - energy bonds found in atp?
2. what helps weaken these bonds so energy can be released and then later help reform them?
3. when atp loses a phosphate group, _ is released for cells and a molecule of _ forms.

in figure 4, color the 5 - carbon sugar red and label it ribose. color and label the nitrogen - base dark blue. color and label the 3 phosphate groups yellow, and color & label the 2 high - energy bonds green.
figure 4 - atp molecule
questions:

1. what is the energy molecule of the cell called?
2. what macromolecule made by plants is \burned\ in the mitochondria?
3. where is chlorophyll found in the chloroplast?
4. in which part of a plant would you expect to find the most chloroplasts and why?
5. how would the number of mitochondria in an insects wing compare to the amount found in other cells in an insects body? explain your answer

Explanation:

1. High - energy bonds in ATP are between phosphate groups.
2. Enzymes like ATPase weaken the bonds to release energy and ATP synthase helps reform them.
3. When ATP loses a phosphate group, energy is released and ADP (adenosine diphosphate) forms.
4. The energy molecule of the cell is ATP (adenosine triphosphate).
5. Glucose, a macromolecule made by plants, is "burned" in the mitochondria.
6. Chlorophyll is found in the thylakoid membranes of the chloroplast.
7. The most chloroplasts are found in the leaves of a plant because they are the main site of photosynthesis.
8. The number of mitochondria in an insect's wing is likely higher than in other cells in an insect's body because the wing requires a large amount of energy for flight.

Answer:

1. Between phosphate groups.
2. Enzymes (ATPase to break, ATP synthase to reform).
3. Energy; ADP.
4. ATP (adenosine triphosphate).
5. Glucose.
6. Thylakoid membranes.
7. Leaves, as they are the main site of photosynthesis.
8. The number of mitochondria in an insect's wing is likely higher as the wing requires a large amount of energy for flight.
