There are more than 2. Any molecule with a negative charge is an anion. Inside cells, these include bicarbonate, chloride, ATP, and any other molecule with phosphate groups, and amino acids having negative charge (glutamate, aspartate). So, there are a wide variety of intracellular anions.
What else can I help you with?
Is proteins the major intracellular anion?
No; the major intracellular anion is phosphate.
What would happen to a resting membrane potential if the concentration of a large intracellular anions that are unable to cross the membrane experimentally is increased?
If the concentration of large intracellular anions..i.e. proteins, which are unable to cross the membrane due to their large size.. were to increase, the resting potential would reach a more negative state, a deviation from -70mV to a more negative value do to these anions.
What is intracellular anion?
Extracellular ions are ions found outside of a cell or tissue. This includes things in the interstitial spaces and fluids, ions in your blood, lymph and other fluids that help cushion or provide nutrition for a tissue.
What is chief intracellular cation?
The chief intracellular cation is potassium (K+). It plays a vital role in maintaining cell function, including membrane potential and cellular signaling. Potassium is involved in various cellular processes such as muscle contraction and nerve transmission.
What is the major ingredient of fluid inside of cells?
Water (H2O) Salt (NaOH & KOH). Note, in mammalian cells, the intracellular and extracellular potassium and sodium levels are different. Potassium - Intracellular 139 millimolar, extracellular 4 millimolar Sodium - Intracellular 12 millimolar, extracellular 145 millimolar
Are eubacteria intracellular or extracellular?
intracellular
Main intracellular ion maintains icf osmotic pressure?
Potassium ions are the main intracellular ion that helps maintain osmotic pressure in the intracellular fluid (ICF). Potassium plays a crucial role in regulating cellular water content and facilitating proper cell function. Any imbalance in potassium levels can affect cell volume and disrupt normal cellular processes.
What is the major ingredient of the fluid inside cells?
Water (H2O) Salt (NaOH & KOH). Note, in mammalian cells, the intracellular and extracellular potassium and sodium levels are different. Potassium - Intracellular 139 millimolar, extracellular 4 millimolar Sodium - Intracellular 12 millimolar, extracellular 145 millimolar
What separates the intracellular and extracellular fluid compartments?
Cell membranes separate the intracellular and extracellular fluid compartments. The intracellular fluid is contained within the cells, while the extracellular fluid surrounds the cells. Transport proteins in the cell membrane regulate the movement of substances between these compartments.
What is the major cation in the intracellular fluid?
potassium
Do mollusks undergo extracellular digestion or intracellular digestion?
Intracellular
What is the major intracellular buffer and what function does its equilibrium provide?
The major intracellular buffer is the bicarbonate-carbonic acid system. Its equilibrium helps to maintain the pH balance within cells by accepting or donating protons (H+) to prevent excessive changes in acidity or alkalinity. This buffer system is vital for regulating cellular functions and maintaining homeostasis.
