Answer:
The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value. The mean lifetime (τ, “tau”) is the average lifetime of a radioactive particle before decay. The decay constant (λ, “lambda”) is the inverse of the mean lifetime
Answer:
The three products of cellular respiration are:
- ATP
- Water
- Carbon dioxide
Explanation:
- Cellular respiration is the process of breaking down glucose molecules to yield energy in the form of ATP.
- C6H12O6 + 6O2 → 6CO2 + 6H2O
ATP Production:
- The first step of cellular respiration, glycolysis, yields 2 net ATP.
- The second step, Kreb's cycle produces 10 NADH and 2 FADH2 molecules. Both these molecules store energy that is released in the electron transport chain to produce 34 ATP.
- Therefore, a total of 36 ATP are produced as a result of cellular respiration in eukaryotes.
Carbon dioxide Production:
- 2 molecules of CO2 are produced during the conversion of pyruvate into Acetyl Co-A by the <em>pyruvate dehydrogenase</em> complex.
- 4 molecules of CO2 are produced in the Kreb's cycle.
Water Production:
- Water is produced in the Electron Transport Chain (ETC) by the reduction of oxygen.
Explanation:
In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.
