Answer:
Photosynthesis consist of two types of reaction 1 light dependent reaction 2 light independent reaction or dark reaction.
Explanation:
light dependent reaction
light dependent reaction or light reaction occur in the thylakoid of granum of chloroplast.During light reaction light energy is absorbed by various pigments of the photosystem and is finally converted into chemical energy.
During light reaction water is split in presence of sunlight to form H+ and OH- ions.The OH- ions releases electron.The released electron is then transported through various electron carriers resulting in the formation of ATP molecule by cyclic photo phosphorylation and NADPH by noncyclic photophosphorylation.
Light independent reaction
Light independent reaction or dark reaction occur in the stroma of chloroplast.The ATP and NADPH that is formed during light reaction is used as 3:2 ratio for per molecule of glucose production.
Answer: Option B
Explanation: If all the cheetahs from the savanna is removed then the population of the gazelle will increase.
The shrubs and trees are producers that is eaten up by the herbivores animals. They at not eaten by the cheetah.
The lion is also not eaten up by the cheetah. There will be no effect o the population of the lions.
Hence, there will be an increase in the population of the gazelle.
Perhaps Meiosis or Mitosis.
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Answer:
d. on the plasma membrane
Explanation:
According to the endosymbiotic theory the origin of mitochondrion is from the prokaryotic organism: primitive host cell (future eukaryotic cell) engulfed prokaryotic cell (endosymbiont) that provided the functions that evolved into mitochondria. Both of them had benefits: the endosymbiont gained protection and some essential nutrients from the host, while host had the energy and oxygen source from the endosymbiont.
So, the plasma membrane of the endosymbiotic prokaryotic cell became the membrane of the mitochondrion.
