WHAT ARE THE FUNCTIONS OF PROTEIN IN ANIMALS

-Replacement of worn-out or damaged tissues -Maintenance of the composition of protoplasm -Used in construction of cell structures such as microfilaments and microtubules -Formation of enzymes which speeds up the rate of reaction. -Maintenance of homeostasis -They control chemical reactions and metabolic processes -Hormones which are proteins regulates physiological processes such as growth and reproduction.

What are the characteristics of vertebrates?

CHARACTERISTICS OF SUB-PHYLA VERTEBRATA -They have jointed internal skeletons of bone and cartilage -Bilaterally symmetrical -They have well  developed sense organs (namely; eyes for vision, olfactory organs for smell, auditory organs for hearing, taste buds for tasting and tactile organs for touch) -They have “closed” blood system -Alimentary canal has several distinct regions the head …

What’s a competitive inhibitor?

COMPETITIVE INHIBITOR -Occurs when the inhibitor has a similar molecular configuration as the normal substrate (i.e its shape resembles the enzyme’s normal substrate). -Consequently the inhibitor competes with the normal substrate to occupy the active site -It prevent the enzymes from combining with the normal substrate and the reaction the not proceed. -The degree of …

Principle of Phototropic and Geotropic movement in plant.

Phototropic movement: Shoots are positively geotropic. Roots are either negatively geotropic or do not respond at all .In roots ,growth is slower on the illumina4ed side relatively to the dark side, with the result that the shoot bends over towards the light. Quantitative experiments in which shoots are subjected to light and varying intensity and …

Relationship between biochemistry and medicine

Biochemistry and medicine Introduction Biochemistry is the science concerned with the various molecules that occur in living cells and organisms and with their chemical reactions. Anything more than a superficial comprehension of life-in all diverse manifestations-demands a knowledge of biochemistry. Medical students who acquire a sound knowledge of biochemistry will be in a strong position …

Ecology of Population

Population ecology is a field of ecology that deals with the dynamics of species populations and how these populations act together with the environment. In population ecology, density-dependent processes take place when population growth rates are synchronized by the density of a population. Even though population ecology is a branch of biology, it makes available …
