How Germination And Temperature Of Environment Effect Respiration Rate Of Seeds
To determine how germination and temperature of environment effect respiration rate of seeds.
Cellular Respiration: Is the controlled release of energy from organic compounds in cells to form ATP. Sugar + Oxygen → Carbon dioxide + Water + Energy (ATP). In eukaryotic organisms, respiration occurs to maximize ATP production; this is contrary to anaerobic respiration, which occurs during the absence of a ready supply of oxygen (mostly in prokaryotic organisms). Plants are autotrophs, meaning that the provided their own food. This is unlike animals, who need to digest other organisms for energy. Because of the autotrophic nature of plants, they perform photosynthesis and cellular respiration simultaneously.
Glycolysis proceed cellular respiration, and it is the process in which glucose, which is produced by the plant itself, is converted into pyruvate. This process also produces a net yield of two ATP and two (NADH+ + H+) and this process occurs in the cytoplasm. Aerobic respiration occurs in a plants mitochondrion, using the pyruvate produced by glycolysis, and aerobic respiration produces large amount of ATP in the presence of O2. This is done via three main processes.
1. The Link Reaction: During this process, pyruvate is transported from the cytoplasm into the mitochondrial matrix. The pyruvate loses a CO2 molecule, and the remaining two carbons are complexed with co Enzyme-A to form acetyl CoA.
2. The Krebs Cycle: occur in the…
