5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

How is the size of a planet related to the thickness of its atmosphere

Butoxors [25]

Many planets are made of gas, and in different situations, the atmosphere can be destroyed.

The sun which is burnt measures atmosphere and in the same case planets can be in a good situation on galactic map and a great condition in the atmosphere as well as earth.
For example, the mass of an object can attract a smaller object causing gravity. The bigger the masses of a planet when it is in the right condition the more atmosphere it can attract if there is any floating on the planet. If it is big it will make a gravitational influence and gather more gases.

Hydrogen ions are important in the light-dependent reactions of photosynthesis because they produce a

Mnenie [13.5K]

Answer:

a. the production of ATP

Explanation:

Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,

Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
NADPH is generated from NADP+
