Cell Wordle
Cell fractionation is important for scientists to study the function of the major organelles.
Nucleoid is important because it holds the information of the prokaryotic cell including DNA.
cytoplasm holds alot of valuable abundance of membrane organelles with their specialized functions to the cell. Plasma membrane helps the cell by acting as a barrier which controls what goes in and out of the cell such as nutrients and wastes. Ribosomes are essential in the process of protein synthesis.
Smooth ER is important to the liver by detoxifying and its cytoplasmic surface lacks ribosomes.
The golgi apparatus is important because it modifies product of ER and sends them to specific locations.
Chloroplasts are important to the cell because it is the location by which photosynthesis takes place.
Cell wall is important to a plant cell because it protects the cell to prevent excessive water intake which could kill the cell. Transport proteins function by only allowing certain molecules pass through the membrane. Diffusion is when molecules transfer from an area of low concentration to an area of higher concentration. Chemiosmosis is when ATP and Transport proteins couple up as a forceful mechanism to facilitates its travels throughout the membrane.Passive transport is when these molecules move across the membrane. Active Transport allows for the movement of molecules across membrane by aid of expending metabolic energy because it has to go against the concentration gradient.Electron Transport chain helps in facilitating change of electron into oxygen by a multistep process.Chemiosmosis is important because it facilitates movement across a membrane by the allowance of coupling between ATP and transport proteins.Cellular respiration is a catabolic pathway in which oxygen is consumed as a reactant.
