Upgraded B002 Ntbi1003 Role Textk Ions Maintaining
Upgraded B002 Ntbi1003 Role Textk Ions Maintaining — a labelled NEET Biology diagram with a definitions lexicon.
Diagram illustrating the role of K + ions in maintaining turgor pressure. Labelled parts: Phosphate group, Plasma Membrane, Cell Membrane, Gas Exchange, Amino Acid, Phosphate, Biomass, Stomata, K+, high internal turgor, open stoma, versus a potassium-deficient guard cell, low turgor, closed stoma, emphasizing ion gradient. Macronutrients, Energy Roles. A chemical group ( PO 4 3- ) that links nucleotides together to form the sugar-phosphate backbone of DNA and RNA. FYI: The phosphate group provides the negative charge necessary for the structural integrity and stability of the nucleic acid backbone. A selectively permeable biological membrane composed of a phospholipid bilayer with embedded proteins that regulates the entry and exit of molecules. FYI: The Fluid Mosaic Model, proposed by Singer and Nicolson, is the most widely accepted description of its structure. A selectively permeable phospholipid bilayer that regulates the passage of molecules into and out of the cell. FYI: Its structure is best described by the Fluid Mosaic Model proposed by Singer and Nicolson in 1972. The process by which respiratory gases (O a ‚‚ and CO a ‚‚) move between the external environment and the blood. In humans, this occurs primarily across the alveolar membranes. FYI: Gas exchange relies on the partial pressure gradient; gases move from an area of higher partial pressure to an area of lower partial pressure. The monomeric building block of proteins, containing an amino group, a carboxyl group, and a variable R-side chain. FYI: There are 20 standard amino acids that make up the vast diversity of proteins in all living organisms. A chemical group (PO4) that forms a phosphodiester bond between the 3' and 5' carbons of pentose sugars in DNA/RNA. FYI: The negative charge of the phosphate group makes DNA an acidic molecule and gives it an overall negative charge. The total mass of living organisms (or specific groups of organisms) within a defined area or volume at a given time. It is a measure of the total organic matter. FYI: Biomass pyramids typically show a decrease at higher trophic levels due to energy loss. Minute pores in the epidermis of the leaf that facilitate gas exchange and transpiration. The primary intracellular cation responsible for maintaining the resting membrane potential and facilitating the repolarization phase. FYI: High permeability of the resting membrane to K+ is why the resting potential is close to the K+ equilibrium potential. high internal turgor is a labeled feature or concept in this upgraded BioAtlas image: A labeled diagram comparing a healthy guard cell (high internal turgor, open stoma) versus a potassium-deficient guard cell (low turgor, closed stoma), emphasizing ion gradient. open stoma is a labeled feature or concept in this upgraded BioAtlas image: A labeled diagram comparing a healthy guard cell (high internal turgor, open stoma) versus a potassium-deficient guard cell (low turgor, closed stoma), emphasizing ion gradient. versus a potassium-deficient guard cell is a labeled feature or concept in this upgraded BioAtlas image: A labeled diagram comparing a healthy guard cell (high internal turgor, open stoma) versus a potassium-deficient guard cell (low turgor, closed stoma), emphasizing ion gradient. low turgor is a labeled feature or concept in this upgraded BioAtlas image: A labeled diagram comparing a healthy guard cell (high internal turgor, open stoma) versus a potassium-deficient guard cell (low turgor, closed stoma), emphasizing ion gradient. closed stoma is a labeled feature or concept in this upgraded BioAtlas image: A labeled diagram comparing a healthy guard cell (high internal turgor, open stoma) versus a potassium-deficient guard cell (low turgor, closed stoma), emphasizing ion gradient. emphasizing ion gradient.
