The infinitive is the base form of the verb, before the verb is conjugated. For example: to speak, to eat, to live are English verbs in the infinitive form; to + verb creates the infinitive of a verb in English. In Spanish the infinitives of verbs have three diferent endings: ar, er and ir.
Light dependent reactions produce ATP and NADPH from energy captured from light. Therefore without light it cannot proceed. Light independent reactions fix carbon dioxide into glucose using the ATP and NADPH produced in the light dependent reactions. So light independent reactions can occur without light as long as CO2, ATP and NADPH is present.
1. Light Dependent Reactions (LDR) - Needs light to occur. Makes ATP, NADPH, O2. 2. Light Independent Reactions (LIR) - May occur in light or dark. Converts CO2 to sugars. The ATP & NADPH accumulate & diffuse to the stroma where they are used to make sugar. ATP is a short-term energy carrier & main energy source for all cells.
