Part 1: Mitosis and Meiosis Short-Answer Response
Use Ch. 5 of BioInquiry and the “Comparing Mitosis and Meiosis” video as resources for Part 1 of this assignment. Write 75- to 100-word answers to the following questions.
Why are the process of mitosis and meiosis both important to a living organism? Mitosis is the process of asexual reproduction of cells. This process is important in order for living organisms to continue to live. If mitosis didn’t happen the living organisms would die when the original cells died off rather than the original cells making new cells that are exactly the same. Meiosis is the process of sexual reproduction where gametes are produced. This is the process of offspring being made. Animals, humans, and other forms of life that reproduce by meiosis would become extinct without meiosis.
When would an organism need to undergo the process of mitosis? Meiosis? Mitosis is the process an organism would undergo to reproduce the cells needed to live such as any cell that makes replicas of itself in order to continue to live or to repair itself. Meiosis is the process that is required to reproduce offspring. In order for there to continue to be life forms on earth meiosis is important to continue the cycle of life. Both processes of cell production are important. They work differently but has similarities. They are both just important in the cycle of life.
What would happen if meiosis did not occur?
If meiosis didn’t occur it would cause endangerment and extinction of species and life forms. Meiosis is an important process to continue all species that reproduce sexually. Meiosis allows sperm and egg to produce gametes which is the beginning of a baby. Without this process populations in all species would be affected unless the species reproduces asexually. Reproducing asexually means that there is no fusion of gametes to create offspring. Asexual reproduction happens with one parent. It is common in bacteria, fungi, and plants.
Part 2: Photosynthesis and Cellular Respiration Matrix
Complete the matrix. Use the following questions to aid in completion:
What is the purpose of this pathway?
Reactants: What does this reaction need to proceed?
Products: What is produced because of the reaction?
The role of ATP: Does it supply energy or store energy?
Break down one molecule of glucose into two molecules of pyruvate Part of a metabolic pathway involved in the chemical conversion of carbohydrates Mediating biochemical reactions that produce adenosine Triphosphate Provide energy for the light-independent reaction
To make food and carbohydrates can be synthesized
Where it takes place
Matrix of the mitochondrion
ATP, NADH, Pyruvates, CO2, Coenzyme A, PGAL
Acetyl CO-A, Oxaloacetate, Citrate, Alpha Ketoglutarate
Hydrogen ions, Oxygen, NADH, FADH2
Light, water, ADP,
ATP, carbon dioxide, and NADPH
H2O, NADH, ATP
Carbon dioxide and ATP
O2, ATP, NADPH
The role of ATP
Finish oxidation of glucose and produce majority of NADH and the only FADH2 ETS accepts energy from carriers in the matrix and stores it to a form that can be used to phosphorylate ADP, Producing ATP for Energy Transports solar energy in the form of ATP to power other chemical reactions Uses ATP from ETC to convert CO2 into G3P.
