I’m stage 2 of photosynthesis NADP becomes NADPH why?
nignag [31]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.

Select all that apply. Which of the following are not properties of enzymes
AlladinOne [14]
Enzymes are proteins that are biological catalysts

They reduce the activation energy required for a reaction to occur and thus speed up a reaction

Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)

They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's

They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.

They aren't used in the reaction so they're re-usable.

If it isn't one of these then it is not one of the properties of enzymes

Question:

The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

<h3>What is Calvin cycle?</h3>

Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.

The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur.

The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates.

However, the series of reaction is an energy consuming one, which makes use of ATP to occur.

Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.
