Grana is the term that describes stacks of thylakoids.
has tremendous biodiversity and high rates of endemic species: of more than 200,000 known species found on Madagascar, more than 80 percent exist nowhere else. Unique to the island are over 100 kinds of lemurs, over 300 species of frogs, and 33 species of tenrecs, miniature hedgehog-like animals. However, it is one of the most threatened ecosystems on the planet.
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.
The correct answer is option e, that is, the thermal energy that one feels when one put the hand on the ground originates from the Sun.
The Earth's energy budget holds for the equilibrium between the energy received by Earth from the Sun, and the energy Earth radiates back after having been dispersed all through the five constituents of the climate system of the Earth and having thus fueled the so-called heat engine of the Earth. This system comprises the Earth's water, atmosphere, ice, all living things, and rocky crust.
A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women. In children, the threshold for high red blood cell count varies with age and sex.
