Post-translational modifications (PTMs) play a crucial role in regulating protein activity, stability, localization, and interaction with other molecules. They can affect the function and properties of proteins, influencing various cellular processes such as signaling pathways, gene expression, and cell cycle regulation. Understanding PTMs is essential for deciphering the complexity of cellular processes and disease mechanisms.
True. Protein is an essential building material for cells. It is involved in many cellular processes, such as structure, signaling, and enzyme activity.
Nitric oxide (NO) plays a crucial physiological role as a signaling molecule in various biological processes. It is involved in vasodilation, helping to relax blood vessels and regulate blood flow and pressure. Additionally, NO is important in neurotransmission and immune response, as it can modulate the activity of neurons and act as a defense mechanism against pathogens. Its ability to influence cellular signaling pathways makes NO essential for maintaining homeostasis in the body.

The GTPase activity of G proteins allows them to hydrolyze GTP to GDP, turning off their signaling activity. This mechanism helps to ensure that the signaling cascade is properly regulated and limited in duration. If this GTPase activity is impaired, it can lead to prolonged signaling and potential malfunctions in cellular processes.

A protein kinase is an enzyme that adds phosphate groups to proteins, which can change their activity or function. This process, called phosphorylation, is important in regulating many cellular processes, such as cell growth, division, and signaling.
Biologic activity can change the amount of proteins, enzymes, hormones, or neurotransmitters in an organism. These changes can have significant impacts on biochemical pathways, signaling processes, and overall physiological functions within the body.
G proteins are signaling molecules that help transmit signals from outside the cell to the inside, activating various cellular responses. They act as molecular switches that regulate the activity of enzymes and other proteins involved in cellular processes.

Kinases are enzymes that transfer phosphate groups from ATP to protein substrates, altering their activity or function. This phosphorylation event can activate or inhibit the target protein, leading to downstream signaling cascades that control various cellular processes like growth, proliferation, and metabolism. By regulating protein activity through phosphorylation, kinases play a crucial role in intracellular signaling pathways.
