Correct answer: Act as a catalysts in a chemical reactions of cells, interact with specific substrates like a lock and key, can lower the required activation energy for reaction in living organisms

Enzymes are the protein molecules that act as biological catalyst, which speed up the rate of chemical reaction by lowering the activation energy of the chemical reaction which are required to carry out the chemical reactions.

Enzymes are specific in nature, which means they have a specific shape and only a specific substrate will fit into its active site and carry out the reactions.

All the biochemical reactions which are occurring inside the body require enzyme, without enzyme the rate of biochemical reaction would be much slower as compared to the reactions taking place in presence of enzyme.

Example: Lipase:- An enzyme which found in living organism which help in the digestion and processing of lipid, fats and oils.

How is neuron like and different from a blood cell
jok3333 [9.3K]

Answer:

Neurons are similar to other cells because neurons have a cell membrane, a nucleus, cytoplasm, mitochondria, organelles, and carry out processes such as energy production.

Neurons differ from other cells because neurons have extensions called axons and dendrites, they communicate with each other through an electrochemical process which we just talked about, and neurons have specialized structures such as synapses and chemicals such as neurotransmitters.

The structural commonality of the biceps brachii and the rectus abdominis is that they are __________.
Strike441 [17]

The structural commonality of the biceps brachii and the rectus abdominis is that they are parallel muscles whose fibers run along through the long axis of the body.

Together with the pyramidalis muscle, the rectus abdominis is a member of the anterior abdominal muscles. However, when considering the functional architecture, these two muscles, together with the three lateral abdominal muscles—the external oblique, internal oblique, and transversus abdominis make up the anterolateral abdominal wall.

The biceps brachii muscle, also known as the "biceps," is a big, thick arm muscle with two heads. The supraglenoid tubercle, located above the glenoid cavity of the scapula, is the location of the long head. It is extra synovial while being in the intracapsular area.

At the humeral head, the long biceps tendon curves sharply before continuing on in the bicipital groove (intertubercular sulcus). Ligaments in the capsular region (also known as the biceps pulley) hold this pivotal point in place.

Short head: Arises at the coracoid process of the scapula, where it partially fuses with the coracobrachialis origin tendon.
