what are the effects of light energy in an atom?

what is the ATP structure and function

what organelles are involved in photosynthesis and cellular resipiration.

Where do the reactions happen in the chloroplast?

Explain leaf structure photosythesis?

explain pigment molecules and light energy together?

What are the stages of cellular respiration and the inputs and outputs?

explain aerobic vs anaerobic respiration?

What is the Endosymbiotic theory?

Answer 1

During photosynthesis light energy is converted in chemical potential energy and glucose is formed.

During respiration glucose is converted into ATP and this ATP is used by cells of body for work like move muscles.. hence potential energy is converted into kinetic energy during respiration.

Effects of light energy on atom is that a photon when hits a atom it is absorbed and re emitted or it moves the electron to high energy state.

ATP is adenosine triphosphate.it is organic compound that provides energy to drive life processes. It is also called energy currency of cell

Organelles involved in photosynthesis are choloroplasts. And for respiration is mitochondrion.

In choloroplast reaction takes place in thylakoid discs

Leaf has a mesophyll tissue which contain choloroplast .and stomato which are pores for water and gas exchange.

Pigment molecules absorb specific wavelength. These are cholorophyll, carotenoids, anthocyanins,flavonoids.

Stages of cellular respiration are glycolysis, Krebs cycle and electron transport chain.. input is glucose and output is ATP.

In aerobic respiration oxygen is used co2 and water is produced.

. In anaerobic respiration oxygen is not used. Lactic acid is formed.

Endosymbiotic theory say evolution of eukaryotic cells or organelles from prokaryotic ones. Like choloroplasts and mitochondrio they divide by binary fission like prokaryotes.
