Plzzz 1. which of the following substances is needed during light-independent reactions to create glucose during photosynthesis? oxygen solar energy carbon dioxide water 2. water is used during the electron transport chain in while water is formed from the electron transport chain in (1) photosynthesis, (2) cellular respiration (1) cellular respiration, (2) photosynthesis (1) fermentation, (2) anaerobic respiration (1) anaerobic respiration, (2) photosynthesis

For question 1, the correct answer is carbon dioxide.

The light-independent reactions, also known as dark reactions of photosynthesis, refer to the chemical activities, which transform carbon dioxide and other components into glucose. These reactions take place in the stroma, the fluid-filled region of a chloroplast external to the thylakoid membranes.

The answer to the 2nd question is photosynthesis and cellular respiration.

Water is utilized at the time of electron transport chain in photosynthesis. On the other hand, during the process of cellular respiration, both water and carbon dioxide is formed as a waste product.
