Answer:

You watched the lab demo video and looked over the lab sheet.  You saw how the catalyst (MnO2) affected the rate of reaction as hydrogen peroxide (H2O2) broke down in to water (H2O) and oxygen gas (O2).

How did the catalyst affect the rate of reaction?

What was the evidence that the catalyst was having that affect?

Why does photosynthesis require water? a. because water provides oxygen atoms. b. because water provides electrons . c. because
katovenus [111]

Answer:

The correct answer would be b. because water provides electrons.

During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.

The overall reaction can be written as:

2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂

It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.

The oxygen is released as the byproduct of photosynthesis.

The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).

The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.

The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.

The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
