Answer:
Explanation:
1. Depolarizes (depolarization of membrane causes opening of sodium channels which causes outward motion of emphatically charged sodium particles into the grid from the phones. This makes the network be profoundly positive charged and the cell film turns out to be exceptionally contrarily charged)
2. Sodium particles, ECF (As the layer depolarizes, the voltage gated sodium channels situated over the plasma membrane open up and the outwards motion of sodium particle happens deserting an enormous negative charge on plasma layer)
3. Invigorated (the muscle cells contain afferent and efferent neurons which help in transfer of data from muscles to mind and back to muscles. This progression of data happens by the methods for emission of synapses from the mind because of an upgrade)
4. Potassium particles, hyperpolarize (after the activity potential has been played out, the sodium particle channels near forestall further spillage of sodium particles in the ECF. Be that as it may, the potassium channels stay opened for longer occasions and consequently hyperpolarize the layer with a net profoundly negative charge)
5. Resting membrane potential (this procedure is known as transmission of motivation in a cell by a pattern of polarization, depolarization and hyperpolazation)
Answer:
- Liver cells are abundant in SER.
- The testes and ovaries are tissue types whose cells are abundant in SER.
- Cholesterol is made in the SER.
- Phospholipids are synthesized from cytosolic water soluble precursor molecules.
Explanation:
This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.
This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).
ER is the organelle at which all membrane lipids are synthesized.
Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
Answer:
Nucleus
Explanation:
Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.
So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. ... Cells have many parts, each with a different function.
Las células son los componentes básicos de todos los seres vivos. El cuerpo humano está compuesto por billones de células. Proporcionan estructura al cuerpo, ingieren nutrientes de los alimentos, convierten esos nutrientes en energía y realizan funciones especializadas. ... Las celdas tienen muchas partes, cada una con una función diferente.
