What is the carbohydrate formed in photosynthesis? a atp b carbon dioxide c glucose d lactose

The right option of this question is (C).

Plants during the photosynthetic reaction, the energy and carbohydrates produce to maintain their life cycle. The photosynthetic system consists on two part as light-dependent an independent cycle. In the dependent cycle, the plants use the light to generate the energy compounds as ATP to start up the Independent cycle. The independent cycle also known as the Calvin Cycle, the environmental carbon dioxide is fixed to generate the carbohydrates. The most important carbohydrate that generates in this process is the glucose. The plant generates carbon dioxide and lactose is only present in milk.

So, the best option is (C) as glucose.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
