How do enzymes speed up chemical reaction?

Enzymes speed up chemical reactions by providing a lower activation energy barrier for the reaction to occur.

Lower activation barrier means that less energy is required for the reaction to proceed, which in turn increases the rate at which the reaction occurs. Enzymes work by binding to the reactants of a reaction in a specific way, forming an enzyme-substrate complex. This binding causes a structural change in the enzyme or substrate, which reduces the activation energy needed for the reaction to occur.

The active site of the enzyme is where the chemical reaction takes place. This active site contains amino acid residues that help to stabilize the transition state of the reaction, which is the point at which the reactants are converted into products.

Enzymes can also increase the rate of reaction by increasing the concentration of the reactants at the active site of the enzyme, increasing the collision frequency of the reactants, and increasing the local pH, temperature, and pressure.

Enzymes are essential for many biochemical reactions that take place in our cells and are vital for life. Without enzymes, many metabolic processes would be too slow to sustain life and the rate of chemical reactions would be drastically reduced.

In the human body, enzymes function as catalysts to speed up reactions by helping to lower the activation energy needed to start a reaction.

Although some RNA molecules can also act as enzymes, proteins constitute the vast majority of enzymes.

The primary function of enzymes is to decrease the activation energy, or the energy required for a process to start. Enzymes bind to reactant molecules and hold them in place to enable the chemical bond-forming and bond-breaking processes.

The energy of the transition state, which products must pass through in order to become reactants, is reduced by enzymes. 

Instead of using energy to move till they collide at random, they might group the reactants together to make it easier for them to interact. They could direct the process along a different pathway with lower activation energy.

By tying them to the active site, they might place the reactants correctly. As a result, the reactants can interact with less energy because they won't have to fight against intermolecular forces that would normally try to separate them.

Temperature, ionic circumstances, and environmental pH all have an impact on how quickly an enzyme.

In ocean waves, water particles move ________ and energy moves ________. A) vertically; in circles B) in circles; horizontally C
son4ous [18]
In ocean waves, water particles move in circles and energy moves horizontally. Ocean waves are orbital progressive waves. The water molecules that make up the wave move in circles, or orbits, as the wave progresses. The ocean orbital waves get their start when wind blows on the open ocean, A gentle wind doesn't have much of an effect, but the stronger wind becomes the more it pushes against the water. It transfers energy to the water as it makes peaks and whitecaps in the water's surface.

Tom [10]

Answer:

oxygen

Explanation:

A limiting factor is any condition whose decrease, increase, absence or presence is able to limit/stop population growth. Examples of limiting factors include abiotic conditions (e.g., temperature, water, oxygen, CO2, etc) or biotic conditions (e.g., food, mate, etc). There are many aquatic species that require high levels of oxygen (e.g., fish), thus being it a limiting factor for these species.

Addison disease
Anna007 [38]

Answer: Addison disease is an adrenal insufficiency. This occurs because of the fact that adrenal gland produces very low quantity of hormones like cortisol, and aldosterone.

Explanation:

1. The symptoms of addison disease are loss of appetite, increased thirst, low mood, and muscle fatigue.

2. The addison disease is an autoimmune reaction, which can affect people of all age groups.

3. It can cause other diseases like tuberculosis.

4. The hormone replacement therapy is ideal for the treatment for addison disease. The use of oral corticosteroids is ideal. The diet containing balanced proteins, carbohydrates, fats, increased intake of vegetables including vitamins, and minerals are necessary for treatment of addison disease.
