Since energy is given to the reactant side, the reaction is endothermic reaction and it is given by ΔH = +393.5 kJ

Therefore option A is correct.

When we write the formula for an ionic compound, we are merely indicate the "molecules" in the compound with that formula. expla
belka [17]
When writing an ionic compound formula, a "molecular" form is used.  The formula is made with allowance for ion charges.
For example,
Ca²⁺ and NO₃⁻ ⇒ Ca(NO₃)₂
Al³⁺ and SO₄²⁻  ⇒ Al₂(SO₄)₃

How are the excited electrons from stage 1 used in stage 2 of photosynthesis? A. Splitting of water b. Carbon fixation c. Format
Gnom [1K]

Answer;

D. Formation of NADPH

Explanation;

During the process of photosynthesis light is converted to chemical energy.

During stage 1, Excited electrons that leave the chlorophyll pigments in stage 1 are used. Excited electrons are passed through proteins in the thylakoid membrane like a ball being passed from person to person. H2o molecules split and turn into H+ molecules and O2 gas, then pigments take the electrons from the split water molecules and release O2 into the atmosphere.

During stage 2; electrons from 1st cluster pump H+ ions into the thylakoid membrane through the hydrogen ion pump (protein membrane. Higher concentration of H+ ions inside the thylakoid membrane compared to outside. H+ ions diffuse out of the thylakoid throught the ATP synthase (enzyme in membrane). ATP synthase catalyzes the reaction ADP + P ---->ATP.

Stage 2; Excited electrons + H+ ions + NADP+= NADPH
