Answer: NADPH and ATP.
The Calvin cycle is a set of reactions that happens as part of photosyntesis, after the energy of the light has been taken. That is whay it is said that the Calvin cycle is independent of light or that it is the dark phase of photosynthesis.
The energy of NADPH and ATP molecules is used during Calvin cycle to fixate the CO2.
Janine is right because CONSUMING TOO MUCH PROTEINS AND NO CARBOHYDRATES WITH PUT MORE PRESSURE ON THE LIVER AND KIDNEY. LIVER AND KIDNEY WILL REQUIRE MORE ENERGY TO BREAKDOWN TOO MUCH PROTEINS. THUS KIDNEY MIGHT GET RUINED DUE TO TOO MUCH WORK.
Carbohydrates, proteins and fats are used as source of energy and converted into energy. Carbohydrates are first to be metabolized for the production of energy. It is readily broken down into simple form. Brain uses only carbohydrate in the form of glucose as energy source. Glucose is used as an immediate fuel.
Protein is used as a source of energy when the body lacks carbohydrates. If protein and carbohydrates are received by the body in sufficient amount, protein is used for other specific purposes. Protein is not reserved for later use and our body do not store protein. It acts as building blocks of body to maintain the proper functioning of the body.
Fats are the last source of energy and used as energy source only in the absence of carbohydrates and proteins. Energy is stored in the body in the form of fat in the adipose tissues for later use in the absence carbohydrates and proteins. This stored fat is broken down into energy during exercise.
How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.
