About this much of the energy released from food molecules during catabolism is released as heat:______.
lorasvet [3.4K]

About this much of the energy released from food molecules during catabolism is released as heat: adenosine triphosphate (ATP)

The Adenosine triphosphate (ATP) is the source of the energy for the use and the storage at the cellular level. The structure of the ATP is a nucleoside triphosphate, consisting of the nitrogenous base (adenine), and ribose sugar, and the three serially bonded phosphate groups

ATP is synthesized in the mitochondria is the primary energy source for the important biological functions, such as the muscle contraction, the nerve impulse transmission, and the protein synthesis

In general, the main energy source for the cellular metabolism is the glucose, which is the catabolized in the three subsequent processes—the glycolysis, tricarboxylic and acid cycle (TCA or Krebs

The greater the concentration of sulfur and nitrogen oxides, the higher the pH of precipitation. True False
OLEGan [10]

False

Nitrogen and sulfur dioxide are acidic oxides in nature. The burning of fossil fuels and other sources are responsible for addition of these oxides in the atmosphere of earth. These oxides mixed with water vapor causes acid rain. Being acidic in nature they will have low pH value. Therefore, greater the concentration of sulfur and nitrogen oxides, will lower the pH value of precipitation.

hope this helps:)sorry if it doesnt

Hydrothermal vents are often rich in metals, such as copper, and also host dense populations of marine organisms. Which of the f
nydimaria [60]

The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
