What was the environment in early earth would we have been able to survive it? Why or why not

Without an oxygen atmosphere very few things could live on the early Earth. Anaerobic bacteria were probably the first living things on Earth. The early Earth had no oceans and was frequently hit with meteorites and asteroids.

Explanation:

In the light-independent reactions, the plant starts with carbon dioxide and ends up with glyceraldehyde-3-phosphate (G3P). It uses ATP and NADPH from the light-dependent reactions as energy sources  

Explanation:

Step 1: CO₂ adds to ribulose biphosphate (RBP) to form a six-carbon sugar that immediately decomposes into two molecules of 3-phosphopglycerate (3-PGA).

CO₂ + RBP ⟶ 2 3-PGA

Step 2. A phosphate group adds to the 3-PGA to form 1,3-biphosphoglycerate (1,3-BPG).

3-PGA + ATP ⟶ 1,3-BPG + ADP

Step 3. NADPH reduces the 1,3-BPG to G3P

1,3-BPG + NADPH ⟶ G3P + NADP⁺

Most of the G3P is regenerated into RBP, but some leaves the cycle to become glucose.
