Diffusion because it will go from high areas of concentration to areas of low concentration
Answer: B) energy released from exergonic reactions.
Explanation:
Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).
Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.
The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
Answer: To
compensate for low concentrations of carbohydrates, the body hydrolyzes TAGs to
free fatty acids and glycerol, the latter of which is provided in ample supply
to feed the -citric acid cycle.
<span>When the body is
under starvation condition, low concentration of carbohydrates occurs, then the
body hydrolyzes triacylglycerols to fatty
acids and ketone bodies. Moreover, the acetyl CoA cannot be transformed into pyruvate so fatty
acids cannot be converted into glucose. The other potential source of glucose
is amino acids but this process is inherently inefficient and weakens
the body so protein must be preserve.</span>
Explanation:
<em>The disadvantage of a closed circulatory system is that with the blood always contained in vessels, it's under higher pressure. This means it can flow faster, which is necessary for supporting the metabolic rate of more complex animals such as vertebrates. Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism</em>.
Answer:
yes
Explanation:
In less than eight months, we used more natural resources than the planet is able to produce in a 12 month period.Of course we need to take care of it. Hope it helps.
