During gas exchange, where does the co2, which is released from the lungs, originate?

The answer is it is a waste product produced by cellular respiration. During Gas exchange in the lungs, oxygen replaces carbon dioxide, and oxygen, oxygenates blood that spreads throughout the body, the Carbon Dioxide, which is expelled from the lungs originated from the cellular respiration, which occurred inside the body.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
