5. During aerobic respiration, how many ATPs are made from one molecule of glucose in most cells?
6. What is the role of oxygen in aerobic respiration?
7. Describe how the ATP is made during chemiosmosis
8. What is produced by yeast cells during fermentation?
9. What are the important end products of the Citric Acid Cycle, and what happens to each of these products?
Here are the photosynthesis questions for review:
1. Which colors of light are most strongly absorbed by chlorophyll?
2. How is oxygen released during photosynthesis?
3. Why is water needed in photosynthesis?
4. What are the products of the light dependent reactions?
5. What is made in the light independent reactions?
6. What is the role of RUBP in photosynthesis?
7. What kind of plants use PEP and what advantage does it give them?
8. How are CAM plants different from others in the way they do photosynthesis?
9. What kind of organisms can do photosynthesis?
10. Where inside the chloroplast do the light dependent reactions happen?
Genetics
1. Which of Mendel's laws addresses homologous chromosomes separating from each other during meiosis?
2. What word (or phrase) describes each of the following genotypes? TT Tt tt
3. What is the difference between genotype and phenotype?
4. In pea plants purple flower color (P) is dominant to white (p). If a plant heterozygous for purple flowers is crossed with a plant with white flowers, what proportion of the offspring will have white flowers?
5. In one species of flowering plants there is some diversity in flower color. Some plants have blue flowers, some have red, and others have purple flowers. What type of inheritance do you suspect controls this trait, and why?
6. Describe Mendel's law of independent assortment.
7. Allele pairs are found on ___________________ chromosomes.
8. In peas, tall plants (T) are dominant to short plants (t), and yellow seeds(Y) are dominant to green (y) seeds. Two plants heterozygous for both traits are crossed. What proportion should be tall plants with green seeds?
9. In one species of plant The flowers can be blue or red. When two blue flowering plants are crossed, the offspring are always blue. When a red and blue flowering plant are crossed, sometimes all red are produced, and other times both red and blue flowering plants are produced. When two red flowering plants are crossed, sometimes the offspring are all red, and other times both red flower and blue flowering plants are made. Which color is dominant?

6. In what biomes does fire play an important role, and what is this role?
7. How are coniferous forests different from deciduous forests?
8. Grasslands have fertile soil, and a wet humid time of the year. Why don't they turn into forests?
9. What do all deserts have in common?
10. In a tropical broad leaf forest, it often rains every afternoon. What do plants in this biome compete for? How are they adapted to compete for this resource?
11. What important role does fire play in a grassland biome?
