What will happen to levels of ATP production in a muscle cell of an individual that stops consuming carbohydrates and other sources of sugar in his diet? A) atp production level will drop to zero and cell will die
B) atp production levels will rise because the cell will use fat to make atp fat has a lot more energy than carbs
C) atp production will drop dramatically cell will have to import glucose from other cells
D) atp production will likely remain the same as the cell can use other compounds that feed into glycolysis and citric acid cycle
E) atp production will stay the same over a short time until all glycogen storage granules are depeleted and then atp production will stop

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the scientific method.

i think that it is c, d, and e, hope this

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
