explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.

Answers

Answer 1

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

(1 Point)
a) Into the cell.
b) Out of the cell.

Answers

Answer:

a) Into the cell.

Explanation:

The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.

What is plate tectonics?

Tectonic plates are the types of crustal plates that are gigantic pieces of the Earth's crust and uppermost mantle. A crustal plate may be defined as a type of large block or tabular section of the lithosphere that significantly reacts to tectonic forces as a unit and moves as such.

The movement of the crustal plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Due to this, the water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.

Therefore, the correct option for this question is C.

Intercambio de oxígeno y dióxido de carbono

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.

La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.

Intercambio de gases entre las alveolas y los capilares

Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

B. increased water vapor in the atmosphere; increase in severe storms; increased carbon dioxide in the atmosphere; increase flooding

C. increased water vapor in the atmosphere; increased carbon dioxide in the atmosphere; increase in severe storms; increase flooding

D. increased carbon dioxide in the atmosphere; increase flooding; increased water vapor in the atmosphere; increase in severe storms

Answers

Answer:

D

Explanation

carbon dioxide is enhanced by human activity as it icrease it leads to many consequences so B and C are canceled

increasing carbon dioxide does not increase the water vapor immediatly

so A is canceled

so the left answer will be D

The choice that provides the ordering of the chain of events should be option D where the carbon dioxide should be increased.

What is carbon dioxide?

It should be treated as colorless and nonflammable gas at the normal temperature and the pressure. Also it comprise of one carbon atom and 2 oxygen atoms. Here it should be enhanced by the human activity due to which the flooding should be increased, water vapor is also increased also the storms too.

Therefore, the option d is correct.

justify that fluorine cannot exist monoatomic from nature​

Answers

Answer:

Due to incomplete outermost shell.

Explanation:

Fluorine cannot exist monoatomic in nature​ because of its incomplete outermost shell. This incomplete outermost shell makes Fluorine more reactive and it can only be stable if it makes bond with other atoms through sharing of electron i. e. covalent bond or by complete transfer of electron i. e. ionic bond. This bond making completes its outermost shell and the Fluorine attain stability so that's why the Fluorine cannot exists in monoatomic in nature.

On the image, which letter represents the enzyme?

Answers

Answer:The correct answer is B

Explanation:

I hope this helps you out!

From the image, the letter that represents the enzyme is B.

Enzymes are substances, made up of proteins, which are capable of speeding up the metabolic reactions in the human body.

There is a theory that explains the mechanism of action of enzymes. This is called the enzyme lock and key theory.

This theory states that enzymes bind to substrates temporarily forming enzyme-substrate complex that appears like the fitting of a lock and key.

This simply means that the same way a particular key can only fit into a particular lock is the same way a particular substrate must combine with  a particular enzyme for a reaction to occur.

From the diagram,

B represents the enzyme with an active site which must fit into a substrate

A represents the substrate.

Therefore, the the letter that represents the enzyme is B.
