Mitochondria is described as the power house of the cell, because it is the cell organelle that process the production of ATP, which is the energy source of the cell. Kreb's cycle occurs in the mitochondria, it is the process by which energy is generated inside the cell, leading to the production of ATP and carbon dioxide and water are given up as waste products.
Answer: Oxygen
Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.
Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.
1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.
2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.
Answer:
SARS- CoV- 2 is a virus that infects human by the oral-respiratory way in which the virus enters the body and these viruses have spikes on their surface made of spike proteins that allow these viruses to bind with the infected cell.
The infected cells have ACE2 receptor that is protein present on the surface of the human cells. Binding allows the structural change in the virus to fuse and enter in the cell where viruses reproduce them selves with the cell with cell system.

i just finished the quick check this is the right answer
hope this helps :)sorry if it doesn't
Answer:
Protein found in antibodies provides the immunity to our body to fight against any foreign antigen.
Explanation:
- Protein is the building block of our body. It forms the body tissue and even acts as a fuel source.
- But protein found in antibodies are slightly different in their function. In antibodies, protein develops the immunity power that shields our body from the external antigens that may cause dysfunction in our body.
- These antibodies drags out any antigens attacking our body systems.
