Does decaying organic matter and animal waste add CO2 to the atmosphere ?

ivanzaharov [21]

In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. ... After death, decomposition releases carbon into the air, soil and water.

Which statements about the production of ATP ATP in chloroplasts are true? The production of ATP ATP in chloroplasts does not re

Lostsunrise [7]

Answer:

A proton gradient is generated by the transport of protons into the thylakoid lumen.

Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.

Explanation:

During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).

Explain fetal circulation in easy way so that all can understand easily

lisabon 2012 [21]

Answer:

In animals that give live birth, the fetal circulation is the circulatory system of a fetus. The term usually encompasses the entire fetoplacental circulation, which includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.

erastovalidia [21]

Explanation:

-The increased light intensity increased the rate of photosynthesis.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. Since photosynthesis is rate limited, the rate of energy intake can be increased in order to speed up photosynthesis, by speeding up photolysis.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Respiration and photorespiration both utilize oxygen for;

the production of ATP via the oxidization of pyruvate;
and the oxygenation of the molecule Ribulose 1,5-bisphosphate (RuBP), an organic molecule also used in photosynthesis, to form 3-PGA + phosphoglycolic acid,

∴ the rate of CO2 usage for photosynthesis where O2 is produced, outpaces the rate of O2 use in respiration and photorespiration.
