Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.
Answer:
Explanation:
Plants, algae, and some kinds of bacteria have the ability to photosynthesize. They have special organelles called chloroplasts.
These organelles are the site of <u>photosynthesis</u>. They contain green pigment known as chlorophyll which can capture sunlight. The light energy plus carbon dioxide and water are converted into glucose and oxygen.
The glucose becomes the organism's food and energy source, but the oxygen is just released as a waste product.
