Which wavelength in photosynthesis which has the highest amount of energy?
algol13
Violet and blue have the high frequencies (thus energy) of visible light. Red will be the least energy but lowest energy. And remember, chlorophyll is green because it reflects green into our eyes. Green is therefore not absorbed, so not used for photosynthesis.

Explain the role of enzymes as biological catalysts that lower the activation energy of a reaction.
tia_tia [17]

Answer:

Enzymes are one kind of protein which functioning as catalyst  that speed up reactions by lowering activation energy.Enzyme accelerate a reaction without altering its chemical equilibrium.

Explanation:

Energy which is required for  start a biochemical reaction is called activation energy.Activation Energy helps to jump and start a thermodynamically favorable reactions.

Enzymes can  many  way to its activation energy.

1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their form in the transition state. This reduces the amount of energy needed to complete the transition.

2.Enzyme create a charge distributor which opposite of transition state his lowers the energy of the transition state and decreases the activation energy.

3.The enzyme may reduce the reaction entropy   by bringing substrates together in the correct orientation to react.

4. The enzyme may provide a completely different chemical pathway for the reaction. It may form new bonds in the ES complex that would be difficult to form without the enzyme.

Differentiate between cell mass and cell number
sergiy2304 [10]

Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
