Answer: Enzymes speed up the reaction rate.
Enzymes are regenerated when the reaction is completed.
Enzymes affect the reaction pathway by forming an enzyme-substrate complex.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Enzymes are biocatalysts and are highly specific in their action. The specificity of enzymes is due to the presence of some specific regions called as active sites. These active sites form weak bonds with substrate molecules.
The specific binding leads to formation of an enzyme substrate complex which accounts for high specificity of enzyme catalyzed reactions.
Once a proper orientation is achieved, substrate molecules react to form products and products leave the enzyme surface as they do not have any affinity towards the enzyme site and are regenerated at the end.
Enzymes work best in optimum temperature and pH range.The enzyme gets denaturated at high pH and temperature.
<em>Answer:</em> 8 (feet)
<em>Explanation:</em>
24 inches = 2 feet
48 inches = 4 feet
12 inches = 1 foot
To find volume you do Base * Width * Height
2*4*1 = 8
Hope this helps!
Answer:
The mass of the block made of lead = 255.6 grams
Explanation:
<u>Step 1</u>: Data given
Density of lead = 11.36 g/cm³
length of the block = 5 cm, 1.5 cm and 3 cm
<u>Step 2</u>: Calculate the volume of the block
Volume = length 1 * length 2 * length 3
Volume = 5cm * 1.5 cm * 3 cm
Volume = 22.5 cm³
<u>Step 3</u>: Calculate mass
Mass of the lead block = density of lead * volume
Mass of the lead block = 11.36 g/cm³ * 22.5cm³
Mass of the lead block = 255.6 grams
The mass of the block made of lead = 255.6 grams
The correct answer is C ) the number of atoms of each element is the same in both the reactants and products.
For example this equation the combustion of methane CH4:
CH4 + O2 → CO2 +H2O
this is not balanced equation:
as we have the no.of C atoms on the right side = the atoms on the left side = 1
but the no.of H atoms on the right side = 2
and no.of H atoms on the left side = 4
so to get the balanced equation we have to make no.of atoms equal on both sides:
So, we put 2H2O instead of H2O
CH4 + O2 → CO2 + 2H2O
now the no of O atoms on the right side = 4
and the no.of O atoms on the left side = 2
so, we put 2O2 instead of O2 to make no.of O atoms equal on both sides
So we finally get the balanced equation:
CH4 + 2O2 → CO2 + 2H2O
-have 1 C atom on both sides
-have 4 H atoms on both sides
-Have 4 O atoms on both sides
So the equation will be balanced when no.of atoms of each element are the same in both the reactants and products
Answer: The destruction of crust occurs at deep-sea trenches. Oceanic rocks are pillow-shaped when formed. Rocks across the ocean floor have alternating magnetic stripes. Younger rocks are closer to mid-ocean ridges.
