name the two stages of photosynthesis and list the starting molecule and ending molecule of each.

Summary - In photosynthesis, light energy is converted to chemical energy and carbon is fixed into organic compounds. Light energy is captured by the living world by means of pigments. The pigments involved in photosynthesis in eukaryotes include the chlorophyll and carotenoids...

When the ribosome has moved sufficiently down the mRNA chain towards 3 end, another ribosome takes up position at the initiator codon of mRNA, and starts synthesis of a second molecule of the same polypeptide chain. At any given time, the mRNA chain will, therefore, ca..

It is so called as it takes place only in the presence of sunlight and hence is a light-dependent reaction. Robin Hill, an English biochemist conducted studies on isolated chloroplasts to understand the mechanism of light reactions. Hence, it is also called Hill's reaction. During this stageh..

>The main function of these two photosystems is to trap lightenergy and convert it into chemical energy (ATP) which is used by living cells. The photochemical phase was explained by Arnon and his co-workers in 1958. Whenever a chlorophyll molecule absorbs a photon of light, it i..

Solid-Liquid Equilibrium - When a solid is heated it starts melting at a certain fixed temperature (melting point). At this stage even when the heating is continued, the temperature does not change until the whole of solid is converted into liquid. The state when solid and liqui..

. These proteins cannot be extracted. Some of the integral proteins have very large molecules that extend throughout the phospholipid matrix, projecting out on both surfaces. These proteins are called tunnel proteins or transmembrane proteins. They are believed to have channels for the pa..

Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it constitutes about 88% by mass of wa..

. The total energy of the system is equal to the sum of the energies of the two H atoms. When the two atoms approach each other, electrons of one atom attract the nucleus of the other atom. Electrons of both the atoms are attracted by both the nuclei. These attractive interactio..

. They are found in very large numbers in cells that are actively taking part in photosynthesis. For example, the palisade parenchyma cells in the leaves of dicot plants contain as much as 500 to 600 chloroplasts per cell. fig. 16.9 - Chloroplast in Section Each chloroplast is b..
