Question

почему в живых организмах реакции протекают с большой скоростью при относительно невысокой температурой и давлении?

Answer 1

Ответ:

реакции в организме катализируются ферментами.

Объяснение:

Ферментативный катализ очень эффективен:  он ускоряет превращения в 10⁶  – 10¹¹ раз по сравнению с реакциями без катализатора.

Answer 2

Why do reactions in living organisms occur at a high speed at relatively low temperatures and pressures?

Reactions in living organisms occur at a high speed at relatively low temperatures and pressures due to several factors. These factors include the presence of enzymes, the specific molecular structure of biological molecules, and the regulation of metabolic processes.

Enzymes: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They lower the activation energy required for a reaction to occur, allowing it to proceed more quickly. Enzymes are highly specific and can catalyze specific reactions, which contributes to the efficiency and speed of biochemical reactions in living organisms.

Molecular Structure: The specific molecular structure of biological molecules also plays a role in the speed of reactions. Biological molecules, such as proteins and nucleic acids, have complex three-dimensional structures that allow them to interact with other molecules in a precise manner. This enables efficient and rapid chemical reactions to take place within cells.

Regulation of Metabolic Processes: Living organisms have evolved mechanisms to regulate metabolic processes. This regulation ensures that reactions occur at the appropriate rate to maintain homeostasis and meet the organism's needs. Enzymes and other regulatory molecules control the activity of metabolic pathways, allowing reactions to occur at the desired speed.

It is important to note that the speed of reactions in living organisms is optimized for their specific biological functions. While reactions may occur at lower temperatures and pressures compared to industrial processes, they are still influenced by the physiological conditions of the organism.

Overall, the combination of enzymes, molecular structure, and metabolic regulation allows reactions in living organisms to occur at a high speed at relatively low temperatures and pressures, enabling efficient biochemical processes to take place.
