Name the four protein complexes that catalyse the redox reactions when energy flows down the energy gradient from NADH to `O_2`.

Why are F_0 - F_1 particles complexes that catalyse the redox reactions when energy flows down the energy gradient from NADH to O_2 ?

What is the energy of activation of a chemical reaction, whose rate constant doubles, when the temperature is raised from 17^@C to 27^@C . Given: R = 8.314 Jk^(-1)mol^(-1) .

What is the energy of activation of a reaction whose rate constant doubles when thetemperature changes from 303 K to 313 K?

Some more examples of redox reaction are as follows. Identify the reductants and. oxidants from them. MnO_2+4HCl rarr MnCl_2+2H_2O+Cl_2uarr

Read the paragraph and answer the questions given below: Renewable energy is energy produced from sources that do not deplete or can be replensied within a human's life time. The most common examples include wind, solar, geothermal, biomass, and hydroelectric power. This is in contrast to non-renewable energy is derived directly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for bioenergy. Not all renewable energy sources rely on the sun. For examples, geothermal energy utilizes the Earth's internal heat, tidal energy relies on the gravitational pull of the moon, and hydroelectric power relies on the flow of water. Name the renewable sources of energy which are not dependent on sun. What are they dependent upon?

Same exampels of redox reaction are given identify the reductants and oxidants from them. 2H_2S+SO_2rarr3Sdownarrow+2H_O

What is the energy in joules, required to shift the electron of the hydrogen atom from the first Bohr orbit to the fifth Bohr orbit and what is the wavelength of the light emitted when the electron returns to the ground state? The ground state electron energy is -2.18 xx 10^-11 ergs.

What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from an energy level with n= 4 to an energy level with n = 2 ?
