Answer:
velocidad de reacción
Explanation:
Las enzimas son proteínas que catalizan reacciones, es decir, aumentan la velocidad de reacción. Si se quiere evaluar el efecto de cambiar el pH en una reacción enzimática, se debe realizar la reacción a distintos valores de pH e ir midiendo la velocidad de reacción. Por lo tanto:
pH: variable independiente
velocidad de reacción: variable dependiente
La velocidad de reacción podría medirse a través de la cantidad de producto que se forma por unidad de tiempo, o a través de la cantidad de sustrato que se consume por tiempo.
The answer is b. For example, nuclear fusion in the sun (an exergonic process) releases energy as light and heat, and powers the initial steps of photosynthesis (an endergonic process).
Answer:
Venous blood
Explanation:
Arterial blood is carrying oxygen to tissues.....after delivering the oxygen it is venous blood and has less oxygen.
The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
