Food provides calories needed by the body for energy. however, the body must use energy between meals when food is not consumed. what is the most likely response of the body when more energy is used than the calories consumed provide? choice 1 to transform stored proteins into carbohydrates for energy choice 2 to increase blood flow to the limbs for energy production choice 3 to release energy from lipids stored throughout the body choice 4 to contract muscles to create heat energy for the body

The correct answer is: Choice 3-to release energy from lipids stored throughout the body.

The first source of energy in the human body are carbohydrates which are hydrolyzed to their monomeric units such as glucose (glucose is then used for ATP production). Since carbohydrate stores are very small, they are used very quickly.

The second source of energy are fats. The human body will produce Acetyl Co A from the fatty acids by the process of Beta-Oxidation. Acetyl Co A then enters the Krebs Cycle (mitochondria) to produce ATP.

The last source of energy are proteins.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
