Answer:
<u>a. the production of ATP</u>
<u />
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+
The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.
An organism can "make a living" and survive in its niche.
It requires energy when a substance must travel against a concentration gradient through the membrane
