Which four chemical elements make up the bulk of a cell dry weight?

As a result of the rich and diverse metabolic processes that make cells work, living chemistry is largely built around carbon, oxygen, nitrogen and hydrogen, with these elemental components serving as the key building blocks making up the cell’s dry weight.

Which elements make up 90% of the body’s mass?

Almost 99% of the human body mass consists of six main elements; namely: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphor; 65–90% of each cell in the body is composed of water, as such, oxygen and hydrogen are among the main constituents of the human body.

What are examples of bulk transport?

Substances that can move via bulk transport are like hormones, polysaccharides, etc. An example of this is the engulfing of pathogens by phagocytes (endocytosis), then the release of the hydrolysed pieces of the pathogen outside the cell by exocytosis.
