What does pinocytosis involve the transport of?
Pinocytosis involves the transport of fluids into a cell. Pinocytosis is when small particles are brought into the cell. It is also a mode of endocytosis.
What is the name for the process in which food is brought into the cells during active transport?
Endocytosis is the provess used by the cell to bring in large molecules.
Why is it necessary to have a transport system inside the body of living organisms?
Diffusion (of oxygen etc) takes place across a maximum distance of about 1 cm. Therefore, large organisms need a transport system to carry the oxygen to all cells - and remove the waste (carbon dioxide). The transport system is also used to take cells nutrients - the products of digestion. If this did not occur, only the cells of the lower digestive tract, where nutrient absorption takes place, would get the nutrients they need. Without these nutrients throughout the body, the cells would die. The transport system is also very important in the immune response. It allows white blood cells to get to the site of infection etc. It also is often used to take hormones to their target organs e.g. epinephrine (adrenaline).

Biological study brought about?
First information and then knowledge.
Where is CoQ found in cells?
Coenzyme Q is found in the inner membrane of the mitochondrion and plays a key role in oxidative phosphorylation during cellular respiration. NADH releases electrons which are transferred to coenzyme Q via NADH dehydrogenase. Coenzyme Q then carries the electrons to the cytochrome bc1 complex. Electrons are also transferred to coenzyme Q by FADH2. The electrons are then brought to the cytochrome bc1 complex like before. This process of transferring electrons is known as the electron transport chain and is ultimately a part of oxidative phosphorylation which is the formation of ATP from ADP and an inorganic phosphate.
Which American idea defeated German U-boats?
Escort Carriers. This brought airplanes into the killing grounds. Planes launched from carriers hunted down their prey.
What happens to atoms during ionic bonding?
During ionic bonding, atoms either lose electrons (if they are metals), or gain electrons (non-metals). The atoms now become charged ions, as there is an imbalance of protons and electrons. For example, sodium and chlorine are very, very reactive on their own, but when brought together, the sodium loses one valence electron, whilst the chlorine gains this single electron. The resulting compound is sodium chloride, which is stable, now that the ions have a full outer electron shell. For more detail, see accompanying link.
What transport did the red fox get to Australia?
They were brought in on ships.
Why do covalent molecules have no charge?
Because in a covalent bond, the electrons are shared within the molecule. There is no lone electron that makes the molecule to be charges. Remember that to conduct electricity, ions should be used because they have charges. Charges are brought about by incomplete or have additional electrons. But with a covalent bond, the electrons are already happy in the molecule that no one is left out to look for another one to attract to.
Why was JJ Thompson important?
JJ Thompson is a Famous Inventor. JJ Contributed to the Atomic Theroy.
If a positively charged conductor was brought in contact with the earth it has .?
gained electrons
What happens immediately after pyruvate brought into the mitochondrion?
Acetyl CoA forms.
What does pinocytosis involve the transport of?
Pinocytosis involves the transport of fluids into a cell. Pinocytosis is when small particles are brought into the cell. It is also a mode of endocytosis.
What will happen to the electrons in a neutral object if a negatively charged balloon is brought near the object?
The electrons are repelled by the negatively charged balloon.
How doping change structure of semiconductor?
This is copied from a similar question to yours fyi. Using boron, phosphorus, and silicon as examples. P-type doping is a process where a silicon atom in the lattice is replaced by a boron atom. A Boron atom has 3 electrons in the outer shell, compared with an electron occupancy of 4 for a silicon atom. So a Boron atom provides a vacancy for any free electrons to occupy with a little effort, when an electron chances to be nearby (the four boron-silicon covalent bonds needs 8 electrons to be stable, but only 7 are provided). The net charge of the material is still zero. More about from where the free electron is coming. N-type doping is using a phosphorus atom to replace a silicon atom. A phosphorus atom has 5 electrons in the outer shell. So a phosphorus atom provides an electron that can be freed with a little effort (the four phosphorus-silicon covalent bonds only need 8 electrons to be stable, each atom needing only to contribute four electrons; the 9th electron will be loosely bound). The net charge of the material is still zero. Where can the electron go? Magic happens when p-type silicon is brought in contact with n-type silicon to form a pn junction. The excess electron vacancies (holes) in p-Si now can exchange with the excess electrons in n-Si, but the net charge of the p-n silicon entity is still zero. However, microscopically, a depletion region is formed at the pn junction, where excess carriers can cross over to the other side. In the p-Si, excess electrons from the n-Si start filling up the holes (the lack of the 8th outer-shell electron to form the four stable boron-silicon covalent bonds) and negatively-charged boron atoms are formed. In the n-Si, excess holes from the p-Si start swallowing up the loosely-bound electrons (the 9th electron in the outer shell) of phosphorus atoms and positively-charged phosphorus atoms are formed. Once formed, and in the absence of an electric field, the depletion region now presents an energy barrier to any further carrier movement and a steady state results -- no net current in the pn junction.
What is the cellular respiration and photosynthesis process?
light strikes photosystem 2, exciting the electrons. The electron come from a water molecule that has been split into hydrogen and oxygen. That is the first reactant (water), and Oxygen gas is given off as the first product. The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The electrons are then passed, at the end of the transport chain, to photosystem 1, where they are re-excited by light. The electrons are passed down another short electron transport chain, which pumps a few more H+ into the thylakoid space, then the electrons get passed to a molecule of NADP+, which is reduced to NADPH. NADPH is a product, NADP+ a reactant. The H+ in the thylakoid then diffuse back into the stroma through a molecule of ATP Synthase that is a channel through the memebrane of the thylakoid. As they pass through the ATP synthase, the H+ make the ATP Synthase go into it's active conformation so it is able to turn ADP into ATP. ADP is a reactant, ATP is a product. To sum it all up, H20, NADP+, and ADP are reactants, and oxygen, NADPH, and ATP are products.
