Describe the three stages of Calvin cycle? |
The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. |

ID the phases of cellular respiration |
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. |

Explain how electrons lose energy as they move down the electron transport system in the formation of ATP? |
The electrons move through the electron transport chain, pumping protons into the intermembrane space. When these protons flow back down their concentration gradient, they pass through ATP synthase, which uses the electron flow to synthesize ATP from ADP and inorganic phosphate |

Identify the components of the cell cycle? |
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions. On the basis of the stimulatory and inhibitory messages a cell receives, it “decides” whether or not it should enter the cell cycle and divide. |

Differentiate between cell reproduction of a prokaryotic and eukaryotic cell type. |
Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. |

ID the stages of mitosis |
Prophase - the nuclear envelope starts to dissociate into small vesicles anaphase -the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle telophase -the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. interphase -the cell undergoes normal growth processes while also preparing for cell division Metaphase - the spindle reaches maturity and the chromosomes align at the metaphase plate (a plane that is equally distant from the two spindle poles). |
