Which of the following is not a product of the light reactions of photosynthesis? 1) NADPH 2) NADH 3) ATP 4) Oxygen

Biology
1 answer:
n200080 [17]3 years ago
5 0

Answer:

The correct option is number 2. NADH is not  product of light reactions of photosynthesis.

Explanation:

The light energy from the sun is captured by the pigmented molecule, chlorophyll, of the plants. This light energy is converted into chemical energy by a serious of light-dependent reactions. The main products of light-dependent reactions are the energy molecule ATP and NADPH. Oxygen is released as a by-product during photosynthesis. Hence, all the option 1,3 and 4 are produced during the light reactions except for option 2 i.e NADH.

1. The correct answer is pH.

The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.

Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.

2. The correct answer is temperature.

Enzyme is sensitive to the environmental conditions such as temperature changes.

Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
