Enzymes actually catalyses the chemical reaction so as function as catalyst.
It is used to speed up the chemical reaction.
C.<span>Without enzymes, chemical reactions would not occur quickly enough to sustain life ,is the correct answer.</span>
<h2>Answer:</h2>
Option B is correct.
B. In an exothermic reaction, excess energy is released as heat.
<h2>Explanation:</h2>
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.
Answer:
16.66 %
Explanation:
The receptors that are bound with the ligand can be calculated by the formula as follows:
Kd = [R] [L]/[RL]
Here, Kd is dissociation constant = 1.5 mM
R is free receptor concentration = 10 mM
L is free ligand concentration = 2.5 mM
The values needs to be constitute to find the percentage of receptors that are bound to ligand.
Put all the values
1.5 = 10 × 2.5 / RL or RL = 25 /1.5
So RL = 16.66
Hence 16.66 % of receptor is bound to substrate.
Thus, the answer is 16.66%
Deforestation is people cutting down whole forests of trees, andmaking it even less likely for humans to survive. Trees supplyoxygen, absorb carbon dioxide, and hold down the soil from washingaway or making landslides. The destruction and cutting down of forests is often done to clearland for farming, mining, roads, and grazing of cattle. That causesincreased atmospheric CO2 levels, a factor in global warming. The Cutting down and clearing of trees The action or process of clearing forests_ also _The state ofhaving been cleared by forests. Verb. To Clear of Forests or trees . The conversion of forested areas to non-forested lands. e.g. Cutting down a forest to make pastures. the cutting down of trees is called deforestation Deforestation means clearing of forests and using that land forother purposes. defforestation is cutting of trees. deforestation is when rain forests get destroyed and ruined 1. The state of being clear of trees 2. The removal of trees Deforestation occurs to create open space for urban or agricultural use.
Yes, while multicellular organisms remove waste through the urinary system, single celled organisms expel their metabolic waste with vacuoles
