Biological fluids regulate ph values using __________. This is achieved by accepting _________ when ph is low and donating _________ when ph is high.
Biological fluids regulate pH values using buffers. This is achieved by accepting H⁺ ions when pH is low and donating H⁺ ions when pH is high.
pH is the potential of hydrogen, that gives an idea about the acidity of basicity of a solution. pH can have values ranging from 0 to 14. A pH value of 7 is neutral. Values below 7 are acidic and values above 7 are basic.
Buffers are the solutions that have the ability to resist any change in pH when any acidic or basic component is added to them. A buffer solution consists of a weak acid and its conjugate base or vice versa. The human body consists of natural buffer, which is blood.

Translation of mRNA- There are two main components to it: a big and a small subunit. The transfer RNAs, or tRNAs, that are floating in the cell are brought together with the mRNA to be translated by the ribosome. mRNA and the polypeptide chain that the cell must assemble are coordinated by adaptor molecules called tRNAs.
Translation of amino acid- As ribosomes move along an mRNA strand during translation, they assemble the sequence of amino acids specified by the mRNA to create a protein with the aid of proteins known as initiation factors, elongation factors, and release factors.
UAC serves as the anticodon for AUG. This tRNA is bringing in a methionine at its other end and has the anticodon UAC. No water molecule is produced as UAC is the first amino acid.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. In what location of the cell would you begin this observation?.
You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. Endoplasmic reticulum (ER) is the place where this observation will begin.
As all enzymes are proteins hence we will begin with the endoplasmic reticulum to study the whole process from the formation of enzymes. The endoplasmic reticulum is the site that plays a central role in the synthesis of a protein.
Ribosomes, the sites where proteins are formed after the translation of mRNA, are present on the membranes of the rough endoplasmic reticulum (RER). After the synthesis of a protein, the rough endoplasmic reticulum (RER) also transports the proteins to the Golgi apparatus where the protein is packaged and processed.

A hormone will have two opposing actions in two different cell types based on the receptors present for that hormone on these cells. The receptors for epinephrine in the muscle cells activate a signaling pathway that stimulates the production of glycogen.

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. One hormone could have opposing effects on different organs as e. cells in the different tissues would have epinephrine receptors coupled to different signaling pathways.
Hormones can help a cell to perform various specialized functions after it activates the receptors of the cell through which signal pathways are activated for the cell.
The receptors of a cell are linked to different cell signaling pathways and this is the reason that a hormone can produce two opposing effects in different types of cells.
The epinephrine hormone activates receptors of muscle cells that help in signaling pathways for the production of glycogen. The same epinephrine, in the airways, couples with a receptor that activates an inhibitory pathway for muscle contraction.
