Answer:
ATP acts as source of energy in several cellular and physical processes happening within the body.
Explanation:
The major functions of Adenosine Tri Phosphate (ATP) are –
a) ATP provides energy for cellular metabolic processes.
b) ATP assists in active transportation of macromolecules across the cell against the concentration gradient.
c) ATP functions in both extra and intracellular signaling by releasing itself from synapses and thereby modulates calcium and cyclic AMP level inside the cell.
d) Maintain the structure of the cell
e) Provides energy for muscle contraction by binding to the myosin
Answer:
True, polar covalent bond
Explanation:
A covalent bond is one of the types of the chemical bond which is formed when the electrons are shared between the two atoms.
Based on the magnitude of the sharing of electrons between atoms two types of covalent bonds are formed which are: pure covalent bond in which the electrons are shared equally whereas the polar covalent bond in which the electrons are shared unequally between two atoms.
Since there is a type of covalent bond formed which has unequal sharing of electrons called polar covalent bond therefore true is the correct answer.

The right answer is the activation energy.
The catalyst increases the reaction rate by introducing new reaction paths (mechanism), and lowering its activation energy, or activation Gibbs free energy. By doing this it can increase the speed, or lower the temperature of the reaction. It is important to note that the catalyst does not alter the total Gibbs free energy of the reaction which is a system state function and therefore has no effect on the equilibrium constant.
Answer : The correct option is, the activation energy
Explanation :
Activation energy : Activation energy is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy.
During the chemical reaction, the reactants react to form product. When a catalyst is added to a chemical reaction then the reaction becomes faster that means the rate of reaction increases and the activation energy decreases.
In the given diagram, 'G' is the activation energy without catalyst and 'H' is the activation energy with catalyst.
The energy diagram is shown below.
