A. diffusion is passive transport, whereas osmosis is active transport. B. only in diffusion do molecules move from areas of high concentrations to areas of low concentration. C. only diffusion refers to the movement of materials across a semipermeable membrane. In cellular biology, membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes, which are lipid bilayers that contain proteins embedded in them. The regulation of passage through the membrane is due to selective membrane permeability - a characteristic of biological membranes which allows them to separate substances of distinct chemical nature. In other words, they can be permeable Which transport process is the main mechanism for the movement of most macromolecules by body cells? asked Oct 14, 2015 in Anatomy & Physiology by Anderson A) secondary active transport Passive transport; Active transport; 1.

Bulk transport refers to the movement of macromolecules

Endocytosis, on the other hand, is the process by which materials move into the cell. What are examples of bulk Exocytosis (/ ˌ ɛ k s oʊ s aɪ ˈ t oʊ s ɪ s /) is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell (exo-+ cytosis). As an active transport mechanism, exocytosis requires adenosine triphosphate (ATP, the body Endocytosis. Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: the plasma membrane of the cell invaginates, forming a pocket around the target particle.

there are two categories of bulk mechanism,_____ and _____. exocytosis and … Read formulas, definitions, laws from Movement Across Cell here.

The regulation of passage through the membrane is due to selective membrane permeability - a characteristic of biological membranes which allows them to separate substances of distinct chemical nature. In other words, they can be permeable Which transport process is the main mechanism for the movement of most macromolecules by body cells? asked Oct 14, 2015 in Anatomy & Physiology by Anderson A) secondary active transport Passive transport; Active transport; 1. Passive transport: Passive transport mechanism does not require cellular energy to transport molecules across cell membrane. So it is a passive process.

Convective oxygen transport refers to the bulk movement of oxygen in air or blood and depends on active, energy consuming processes generating flow in the tracheobronchial tree and circulation. Paracellular transport is a passive transport process that results in the transport of substances across an epithelium by passing through the intercellular spaces in between epithelial cells.
