Biology
1 answer:
german3 years ago
3 0

The correct answer is: D) H2O… CO2

Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).

Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.  

The first step: Oxygen in water is oxidized (light energy required)

The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).

Blizzard [7]

Formed tiny polypeptides known as Proteinoids when they gathered in little pools.

<h3>What is a polypeptide and how does it work?</h3>

Polypeptides. By joining many amino acids together, polypeptides contribute to the creation of proteins. When two or more polypeptides are joined together to form a protein, the resulting structure is unique to that protein.

<h3>What conclusions did Sidney Fox's experiment reach?</h3>

In the 1950s, Sidney Fox demonstrated that when amino acids were splashed in hot, dry circumstances, they immediately polymerized into proteins. Other studies that used cyanide, clays, and heat to cause the polymerization of amino acids into proteins were effective.
