Answer:
Reactions require an input of energy to initiate the reaction; this is called the activation energy (EA).
Activation energy is the amount of energy required to reach the transition state.
The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.
For cellular reactions to occur fast enough over short time scales, their activation energies are lowered by molecules called catalysts.
Enzymes are catalysts
Answer:
Option B
Explanation:
The process of converting a message into a form where it can be transmitted as signals from the sender to the receiver is called as encoding. However, the process of the reconverting the encoded message into intelligible forms so that a receiver could understand the message is called as decoding. However, the entire process of encoding and decoding is known as communication.
For example -
In order to decode a sound signals, analogue from digital are retrieved.
Hence, option B is correct

The 2 substances needed are ADP and NADP.
A. To carry oxygen
