One of the key and defining characteristics of innate immunity is that it creates stronger, faster, and more specific responses to invaders upon repeated exposure/infection.

Immunity is a defense system we are born with and it protects against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. Immunity forms the barrier of first line of defense in the immune response.

Four main components of immunity include effector cells, antimicrobial peptides, soluble mediators, and cell receptors. Innate immune responses rely on the body's ability to recognize conserved features of pathogens that are not present in the uninfected host.

Answer:

Explanation:

Sucrase is an enzyme that hydrolyses sucrose into glucose and fructose. The main function of the enzyme to speed up the biological reaction. As sucrose concentration increased, the reaction will also speed up as long as there is a substrate available to bind. Once all substrate is bound, the reaction will no longer speed up. The reaction will be in constant phase.

At 2.5 to 7.5 g/l sucrase concentration, the reaction will be in early phase. It will give more activity at 22.5 to 27.5 when reaction get stable.
