"Large molecules such as hormones" types of materials are expelled from cells during exocytosis.
<u>Answer:</u> Option A
<u>Explanation:</u>
The mechanism whereby a cell transfers secretory products to the plasma membrane via the cytoplasm is termed as "exocytosis" while material passage into the cell is known as "endocytosis". Exocytosis is need for removing waste material from cell.
In exocytosis, mechanism huge quantity of molecules which means bulk transport is performed.Responsible for secretion of digestive enzymes and hormones. In this process, membranes-bound secretory vesicle pass to the cell membranes while their material like water-soluble molecule get secreted in the extracellular atmosphere.
Scavengers play an important role in the network of food. They keep the world clean from the remains of dead animals, or carrion. Scavengers break down this raw material and recycle it as nutrients into the environment. Vultures consume only the corpses of deceased animals.
Chemistry as a subject has a significant importance in our daily lives and the society in general. Everything on the earth is made of chemicals. ... It also describes various chemical elements preset in the environment, their reactions, and effects on the environment.
Answer:
The correct answer will be option-A.
Explanation:
Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.
The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.
Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.
Thus, option-A is the correct answer.
