Inadequate carbohydrate intake results in the breakdown of body protein for use as fuel. true or false

1 answer:

4 0

The statement is true.
Carbohydrates are broken down in order to obtain glucose for respiration in cells. When there is an inadequate amount of carbohydrates, other macromolecules must be broken down. Excessive breakdown of fats is not possible due to the fact that it causes ketosis; therefore, proteins are broken down and the body starts to lose muscle mass.

What is the importance of ATP and NADPH?

bulgar [2K]

Answer:

The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

These electrons are used to produce NADPH as well as ATP in a series of reactions called the light reactions because they require light. NADPH and ATP formed by the action of light then reduce carbon dioxide and convert it into 3-phosphoglycerate by a series of reactions called the Calvin cycle or the dark reactions.

In animals, nitrogenous wastes are produced mostly from the catabolism of ________. phospholipids and glycolipids proteins and n

guapka [62]

Answer:

Option- "Proteins and Nucleic acid."

In animals, nitrogenous wastes are produced mostly from the catabolism(break down of macro molecules into simpler ones) of Protein molecules.

Explanation:

Proteins and nucleic acids:

Most of the organisms ingest different types of materials. And some of them are proteins which are composed up of different amino acids, as the proteins are important in many ways, they help in cells reproduction and growth etc.

And the nucleic acids are important polymers, which are required for carrying the operation of genetic material from one cell or being to another.Or it may occur simply from one generation to another in the form of RNA and DNA.

Why they are broken down?

Both the polymers consists the Nitrogen atom as the main constituent in there molecular structure, so that is why the break down of these materials results in the form of nitrogenous materials.

When proteins level exceeds from a certain level they need to be controlled and thus required the excessive materials to be excreted from the body. There are different forms or levels of the nitrogenous waste products which are excreted from an animal body. As there levels of organisms excrete them in different forms,which are as below:

Beings living on land and Marine Fish: The nitrogenous waste is excreted mostly in the form of urea or uric acid, but mostly in the urea which is just because they have an optimum level of water as the solvent.Along with that the marine fish can also excretes the nitrogenous waste in the form of trimethylamine oxide.
Ave's(Birds):Birds have a less availability of water in there body which makes them to excrete the nitrogenous waste product in the form of uric acids.
Freshwater Fish: They excrete the amount of nitrogenous waste from the body in form of ammonia, as they have an abundance of water as solvent. While, there is an abundance of water in the environment, which they are able to dissolve the amount of nitrogenous waste products present inside the body and excrete it in the form of ammonia. Which is less toxic form of the nitrogenous waste materials.

UkoKoshka [18]

The membrane bound organelle you refer to is the Lysosome. The lysosome fuses with a vacuole where it digest the contents.
