Answer:

Globular proteins

Explanation:

The cell membrane has phospholipid bilayer which consists of several molecules such as proteins and cholesterol which helps in movement of compounds across the cell membrane through facilitated diffusion.

Globular protein is one these molecules which act as a transport molecule. It has a carbohydrate chain that gets embedded in the cell membrane and help in communicating from one cell to other thereby allowing transportation of large carbohydrate molecule.

julia-pushkina [17]

Answer:

Option (1), (2) and (3).

Explanation:

DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.  

Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.

Thus, the correct answer is option (1), (2) and (3).

Why are pigments such as chlorophyll needed for photosynthesis
Vlad [161]

Answer:

The chlorophyll pigment have photosystem 680/ PS I which captures the sunlight. Then the pigments gets excited and photosynthesis starts. Without chlorophyll photosynthesis can't happen.

Explanation:

Photosynthesis occurs in the chlorophyll pigment of the plant. They have the capacity to trap light energy and convert its energy to form glucose and oxygen.  

The chlorophyll is a double layer membrane structure. In it two photosystems works i.e. photosystem I and photosystem II. In the photosystem I light is trapped.  

In the chlorophyll thylakoids are present which have photosystem 680. It captures the photons coming from the sun. The photons are the light of different wavelengths which are absorbed by plants.  

The photon have more energy, and when it comes in contact with PS 680, the pigments get excited. Then they release high energy electrons which helps to form ATP, NADPH. Because it is a light dependent reaction.

Glucose and oxygen are formed in the stroma as it does not require light. It is a light independent reaction.

Therefore, chlorophyll is first require to capture photons coming from sun.
