Bacterial photosynthesis comes from:
Thus, the correct answer is 'Non-Evolution of O2.'
In cells, ATP is synthesized in:
ATP is synthesized by cells (in mitochondria and chloroplasts) is named phosphorylation.
Which of the following stages of calvin cycle are in CORRECT order?
The Calvin cycle can be described under three stages: carboxylation, reduction and regeneration. Pathway operated in cyclic manner.
Energy obtained from light reaction is transferred to dark reaction in form of:
Energy produced during light reaction is transferred to the dark reaction in form of ATP to fix the carbon dioxide in form of glucose.
Photorespiration does NOT occur in:
Solarisation is the inhibition of photosynthesis at very high light intensities due to photooxidation of certain compounds and destruction of chlorophyll molecules.
Calvin cycle is discovered by:
The work of Melvin Calvin is the discovery that the first CO2 fixation product was a 3-carbon organic acid. He also contributed to working out the complete biosynthetic pathway; hence it was called the Calvin cycle.
Electrons from exited chlorophyll molecules of photosystem II are accepted first by:
In sugarcane, CO2 is fixed in malic acid with the help of enzyme:
In C4 plants, Carbon dioxide is fixed in malic acid with the help of enzyme phosphoenel pyruvate (PEP). Malic acid is a four-carbon compound that later changes into oxaloacetic acid.
Dark fixation of CO2 in CAM plants is called ossification because it produces:
Dark reaction of Carbon dioxide fixation in CAM plants is called as ossification because it produces Malic acid. These plants open their stomata during night to prevent transpiration.
The substances that have an ability to absorb light at different specific wavelength are:
Pigments are substances that have an ability to absorb light, at specific wavelengths. The chlorophyll a pigment to absorb lights of different wavelengths.
Hill reaction requires:
The light-dependent transfer of electrons by chloroplasts in photosynthesis that results in the cleavage of water molecules and liberation of oxygen is called the Hill reaction. Hill reaction required ferricyanide.
On excitation, the electrons picked up by an electron acceptor is passed to:
Electrons become excited and jump into an orbit farther from the atomic nucleus. These electrons are picked up by an electron acceptor which passes them to an electrons transport of cytochrome.
Which one has Kranz anatomy?
In the leaves of C4 plants such as maize, sorghum we can observe the Kranz anatomy.
The law of limiting factors is given by:
When several factors affect any [bio] chemical process, Blackman’s (1905) Law of Limiting Factors comes into effect.
The splitting of water molecule takes place inside:
Splitting of water takes place near PS II, located in the inner side of the thylakoid membrane.
Splitting of water releases oxygen in the atmosphere and generates a proton gradient across the thylakoid membrane.
In PSI, the reaction centre the chlorophyll 'a' has an absorption peak at:
So, the correct answer is 700 nm.
Light reaction otherwise called as:
Light reactions or the ‘Photochemical’ phase include light absorption, water splitting, oxygen release, and the formation of high-energy chemical intermediates, ATP and NADPH. Several complexes are involved in the process.
The C4 pathway is otherwise called as:
The presence of the bundle sheath would help you identify the C4 plants. This pathway that has been named the Hatch and Slack Pathway, is again a cyclic process.
Succulents carry out photosynthesis:
Succulents plants have stomata sunken deeply in the leaf epidermis to prevent loss of water by transpiration. These plants open their stomata during the night and follow the CAM pathway for the fixation of carbon dioxide.
PGA as the first CO2 fixation product was discovered in photosynthesis of:
The splitting of water molecules is associated with:
Light harvesting complexes are made up of:
Light-harvesting complexes (LHC) within Photosystem I (PS I) and Photosystem II (PS II). These are named in the sequence of their discovery, and not in the sequence in which they function during the light reaction. The LHC is made up of hundreds of pigment molecules.
Carbon dioxide is fixed in:
Photosynthesis occurs in two steps- light reaction and dark reaction. During light reaction ATP and NADPH molecules are formed and in dark reaction carbon dioxide is fixed.
Chloroplast dimorphism is a characteristic feature of:
