Along the phosoplipid bilayer numerous blank are embedded within the membrane

explanation:

the phospholipid bilayer is the basic scaffold that makes up the cell membrane. according to the fluid mosaic model, this stent is not static. the phospholipid bilayer is a light oil-like fluid with fluidity. some of the protein molecules are embedded on the surface of the phospholipid bilayer, some or all of which are embedded in the phospholipid bilayer, and some run through the entire phospholipid bilayer. most protein molecules are also mobile.

biocatalysis reactions, involved with natural or engineered enzymes and engineered microorganisms, has large potentials in industry because the use of less toxic reagents and operation under ambient temperature/pressure. hence it is necessary to develop successful large-scale procedures to produce bio-industrial products. yet the challenge to bring a biocatalysis reaction from the laboratory scale to industrial scale is usually enormous. factors including feedstock availability and cost, biocatalyst design, process integration and others need to be considered and optimized.

suitable bioreactors are developed for industrial scale up to support a biologically active environment. they can be categorized into three types: (i) batch fermenters, (ii) continuous fermenters and (iii) recycle reactors. typical examples of them are airlift bioreactors, tower fermenters, plug flow reactors, packed bed bioreactors, fluidized bed bioreactors, stirred tank bioreactors, and others. the size of a bioreactor depends on the purpose of use, varying from 1 liter to more than 500,000 liters. a typical biosynthesis process comprises three steps: (i) upstream processing, such as medium preparation, sterilization, and air purification; (ii) production processing to convert substrates to desired product; (iii) downstream processing, such as separation and purification. each step need to be optimized for various purposes.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
