which organelle produces sugars while releasing oxygen, and in which cell could it be found? a the golgi apparatus, which can be
spayn [35]

Answer:

The correct answer would be d chloroplasts, which can be found in leaf cells of trees.

Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.

They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.

Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.

Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).

The overall reaction is:

6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs.
natali 33 [55]
<span>The answer would be: as the bicarbonate ion in the plasma after first entering the red blood cells

Carbon dioxide will be changed into bicarbonate ion that released into the plasma. That is why the level of carbon dioxide will influence the pH of the blood. The process will produce hydrogen ion so higher carbon dioxide will result in acidosis. It is important to keep the carbon dioxide level at a certain point to prevent blood pH stable</span>
