Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? osmosis passive transport active transport diffusion
Answer: Active Transport
Explanation: Active transport is the movement of a substance (proteins, enzymes, etc.) from one area of the cell membrane to the next during diffusion, so this would most be affected due to the kinds of substances being transported across the cell membrane and damage can have an impact.
Carrier proteins are involved in active transport. The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.
What are the carrier proteins?Carrier proteins are transmembrane molecules involved in active transport.
They carry molecules from one side of the membrane to the other side.
What is active transport?Active transport acts against the electrochemical gradient, so it does need the energy to transport substances.
It carries molecules from a low concentration side to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.
The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.

What is the number of this particle in a phosphorus atom?
Ap ex
Answer:
Fósforo
Símbolo P, número atómico 15, peso atómico 30.9738. El fósforo forma la base de gran número de compuestos, de los cuales los más importantes son los fosfatos. En todas las formas de vida, los fosfatos desempeñan un papel esencial en los procesos de transferencia de energía, como el metabolismo, la fotosíntesis, la función nerviosa y la acción muscular. Los ácidos nucleicos, que entre otras cosas forman el material hereditario (los cromosomas), son fosfatos, así como cierto número de coenzimas. Los esqueletos de los animales están formados por fosfato de calcio.
Cerca de tres cuartas partes del fósforo total (en todas sus formas químicas) se emplean en Estados Unidos como fertilizantes. Otras aplicaciones importantes son como relleno de detergentes, nutrientes suplementarios en alimentos para animales, ablandadores de agua, aditivos para alimentos y fármacos, agentes de revestimiento en el tratamiento de superficies metálicas, aditivos en metalurgia, plastificantes, insecticidas y aditivos de productos petroleros.
De casi 200 fosfatos minerales diferentes, sólo uno, la fluoropatita, Ca5F(PO4)3, se extrae esencialmente de grandes depósitos secundarios originados en los huesos de animales y que se hallan en el fondo de mares prehistóricos, y de los guanos depositados sobre rocas antiguas.
La investigación de la química del fósforo indica que pueden existir tantos compuestos basados en el fósforo como los de carbono. En química orgánica se acostumbra agrupar varios compuestos químicos dentro de familias llamadas series homólogas.
Esto también puede hacerse en la química de los compuestos de fósforo, aunque muchas familias están incompletas. La familia mejor conocida de estos compuestos es el grupo de cadenas de fosfatos. Las sales de fosfatos constan de cationes, como el sodio, junto con cadenas de aniones, como (PnO3n+1)(n+2)-, que pueden tener de 1 a 1 000 000 de átomos de fósforo por anión.
Los fosfatos se basan en átomos de fósforo rodeados en una disposición tetraédrica por átomos de oxígeno, el miembro más pequeño de la familia es el anión simple PO3-4 (el ion ortofosfato). La familia de las cadenas de fosfato se basa en hileras alternadas de átomos de fósforo y oxígeno en que cada átomo de fósforo permanece en el centro de un tetraedro de cuatro átomos de oxígeno. Hay también una familia estrechamente relacionada de fosfatos cíclicos.
Una característica estructural interesante de muchos de los compuestos del fósforo conocidos es la formación de estructuras tipo jaula. Ejemplos de estas moléculas son el fósforo blanco, P4, y uno de los pentóxidos de fósforo, P4O10. Las estructuras tipo red son comunes; por ejemplo, los cristales de fósforo negro en que los átomos están enlazados unos con otros.
En la mayor parte de sus compuestos, el fósforo está enlazado químicamente a cuatro átomos inmediatos. Hay gran número de compuestos en los que uno de los cuatro átomos está ausente y en su lugar hay un par de electrones no compartidos.
Hay también unos cuantos compuestos con cinco o seis átomos unidos al fósforo; son muy reactivos y tienden a ser inestables. Durante los años 60 y 70, se prepararon muchos compuestos orgánicos de fósforo. La mayor parte de estas estructuras químicas incluye tres o cuatro átomos enlazados al fósforo, pero existen también estructuras con dos, cinco o seis átomos unidos a cada átomo de fósforo.
Casi todo el fósforo utilizado en el comercio está en forma de fosfatos. La mayor parte de los fertilizantes fosfatados constan de ortofosfato diácido de calcio u otofosfato ácido de calcio muy impuros, Ca(H2PO4)2 y CaHPO4. Estos fosfatos son sales del ácido ortofosfórico.
El compuesto de fósforo de mayor importancia biológica es el adenosintrifosfato (ATP), que es un éster de la sal, el tripolifosfato de sodio, muy utilizado en detergentes y ablandadores de agua. Casi todas las reacciones en el metabolismo y la fotosíntesis requieren la hidrólisis de este tripolifosfato hasta su derivado pirofosfato, llamado adenosindifosfato (ADP).
Efectos del Fósforo sobre la salud
El Fósforo puede ser encontrado en el ambiente más comúnmente como fosfato. Los fosfatos son substancias importantes en el cuerpo de los humanos porque ellas son parte del material de ADN y tienen parte en la distribósforo que es conocida. Cuando el fósforo blanco ocurre en la naturaleza este puede ser un peligro serio para nuestra salud. El fósforo blanco es extremadamente venenoso y en muchos casos la exposición a él será fatal. En la mayoría de los casos la gente que muere por fósforo blanco ha sido por tragar accidentalmente veneno de rata. Antes de que la gente muera por exposición al fósforo blanco ellos a menudo experimentan náuseas, convulciones en el estómago y desfallecimiento. El fósforo blanco puede causar quemaduras en la piel, dañar el hígado, corazón y riñones.

How would driving from Boston (near sea level) to summit of Mt. Washington affect the rate of oxygen exchange in your lungs? Explain in 1-2 sentences plz
Answer:
The rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington
Explanation:
At near sea level, Boston, where there is sufficient dense air and plentiful supply of oxygen, the rate of breathing and oxygen exchange in the lungs is at normal levels
At the height of 6,288.2 feet, which is the height of the summit of Mt Washington, the lung does more work to extract the oxygen from the air present which is less dense and contains less oxygen than the air at sea level such that a larger volume of air is required to supply the amount of oxygen the body requires
Therefore, the rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington.
