Summary Introduction

To discuss:

The biochemical pathways used by cells to produce ATP.

Introduction:

The metabolism of cells takes place through a series of biochemical reactions, which produces ATP as one of the products. These reactions generate the energy unit ATP, which powers other body functions.

Explanation of Solution

There are two major processes by which the metabolism takes place –catabolism and anabolism. Catabolism is breaking down of nutrients and anabolism is building up of macromolecules. ATP is generated by catabolic pathways. The pathways which generate ATP are:

  1. Glycolysis: Glucose is split into 3 C compound and ATP. The end products of this reaction are pyruvate/lactate and ATP. For every glucose molecule converted into two pyruvate/lactate, 2 ATP molecules are released.
  2. Pyruvate dehydrogenase: 3 carbon compound pyruvate is converted to acetate and carbon dioxide. This reaction is catalyzed by the enzyme pyruvate dehydrogenase which simultaneously converts ADP to ATP.
  3. Beta Oxidation: Fatty acid is broken down acetyl CoA, NADH and FADH. At every step, there is the release of carbon dioxide and energy in the form of ATP. Many units of ATP is released in this process.
  4. Oxidative phosphorylation: This is the ultimate powerhouse of ATP generation. In this process, the NADH and FADH generated in the above pathways react with oxygen to produce water and other end products. This leads to NADH and FADH to get converted to NAD and FAD respectively, at the same time phosphorylation of ADP to ATP takes place.
Conclusion

The above pathways may look independent but in reality, the byproduct of one is used in another. All these work together to generate the ATP in the body.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW).  If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?
None
Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
