OA) sugars and phosphates; nitrogen bases
Answer:- Calvin cycle
Explanation:-
Photosynthesis occurs in two parts:
1. Light dependent reaction which requires sunlight. In this reaction the energy from sunlight gets absorbed by the chlorophyll and is then converted into chemical energy in the form of NADPH and ATP.
2. Light independent reaction which is also known as the calvincycle takes place to provide energy to form carbohydrates using the energized electrons that were obtained from the light dependent reactions. Since, they do not require light for their reaction they can also occur during the night.

T killer cell or Cytotoxic T cells are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.
<u>Explanation</u>:
The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell. The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.
