Although we study the citric acid cycle as the final stage oxidation of carbon from glucose, an in-depth look at the cycle shows intermediates entering and leaving the cycle from a number of metabolic pathways. with all of these demands on the cycle, how does it maintain a minimal level of oxaloacetate (oaa) to allow the cycle to function? a-oaa can be formed by the condensation of two moles of acetyl coa and occurs when the energy charge of the cell is high. b-the rate of the cycle is increased when the cell has high levels of nadh. c-isocitrate dehydrogenase is allosterically inhibited by adp, which signifies the need for more energy. d-oaa is formed directly via the deamination of glutamate. e-oaa is synthesized via pyruvate carboxylase in an anapleurotic reaction that occurs when acetyl coa is present, such as from fatty acid breakdown

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.
