Zak Murdock Pd. 1 10-28-07 Essays 1. Mitochondria are organelles in eukaryotic cells that contain the enzymes of the citric acid cycle, respiratory chain, and oxidative phosphorylation. Glucose can be broken down in order to provide 36 ATP molecules to the cell, which in turn is used as energy. An animal sperm cell would undoubtedly need to contain large amounts of both mitochondria and glucose. A sperm cell is what fertilizes the female egg. By containing large amounts of mitochondria and glucose, the sperm cell is giving the fertilized egg energy through the glucose, and a production factory through the mitochondria. The mitochondria allows for the newly fertilized egg to undergo the citric acid cycle, the respiratory chain, and oxidative phosphorylation. In order for all of these things to be happening, energy is required. The large amounts of glucose provide energy to the fertilized egg in the form of ATP. Without an animal sperm cell containing large amounts of mitochondria and glucose, fertilization most likely would not happen. 2. DNA and RNA are both vital to an organism in order for it function properly. DNA and RNA both contain the nitrogenous bases A, C, and G. However, DNA contains T whereas RNA contains U. DNA also is made up of two strands whereas RNA is only made up of one. Along with the number of strands, DNA and RNA molecules are quite different in shape. DNA molecules take the shape
