The Lock and Key mechanism refer to the action of enzyme. According to this mechanism as a specific key open a particular lock, similarly one enzyme can perform action on one specific substrate (substance).

Answer:

The lock and key mechanism refer to the specific enzyme-substrate reaction mechanism.

Explanation:

The lock and key mechanism explain the specific action of the enzyme on the substrate in a specific reaction. The enzyme is the lock and the key is the substrate. The correctly shaped and sized key that is the substrate, fits into the keyhole which is the active site of the lock that is enzyme as per the lock and key mechanism.

As we know the only a specific key can fit in the keyhole and unlock the lock same action goes with enzyme and substrate, only a specific substrate fits in with the active site of the enzyme in particular reaction.

Thus, the lock and key mechanism refer to the specific enzyme-substrate reaction mechanism.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would

Aleksandr [31]

Answer:

Three different kinds of muscles are -:

SKELETAL MUSCELES
CARDIAC MUSCLES
SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.
CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart.
SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.

What is the difference in inheritance between boys and girls for sex linked traits?

maks197457 [2]

The difference is found in the DNA chromosome of the male and females.
The males have XY chromosomes at the last while the females have XX, these chromosome labels are important to signify deviancy and disparities among the morphology and the later structure of the female and male functions.
