How are muscles able to keep making energy even when no food is eaten and glucose levels are low?
erastova [34]

Although lipids hold the majority of the body's energy reserves, glycogen is the body's primary energy source.

Glucose is a polymer that makes up glycogen. Our body's primary source of energy is carbs. The remaining glucose in the body is turned into glycogen and stored in various places, but the majority of our body's energy reserves are found in fats, which are kept in the form of lipids.

Where does the energy come from in the muscles?

The chemical energy that is stored in our meals is used by muscles to produce heat and motion energy (kinetic energy). Energy is necessary for maintaining body temperature, promoting physical activity, and enabling tissue growth and repair. Foods high in protein, fat, and carbohydrates provide energy.

What Takes Place to Muscles in the Absence of Glucose?

Your body converts carbs, such as those found in bread or fruit, into glucose after consumption. Glycogen is the form of glucose that is stored in your muscles and liver and is used for energy when you are not eating or while you are exercising.

A result of the common-ion effect is ________.
ad-work [718]
A result of the common ion effect is that the selective precipitation of a metal ion, such as Ag+, is promoted by the addition of an appropriate counter ion (X-) that produces a compound (AgX) with a very low solubility.

The splitting of carbon dioxide to form oxygen gas and carbon compounds occurs during
Oxana [17]

Answer:

neither photosynthesis nor respiration.

Explanation:

Photosynthesis is the process by which the green plants, in the presence of sunlight makes their own food. In the process carbon dioxide is absorbed and oxygen is released.

6CO_2 + 6H_2O\ (sunlight)\ \rightarrow C_6H_{12}O_6 + 6O_2

Respiration is the intake of oxygen and the metabolism of the glucose in which it is breakdown and releases carbon dioxide.

C_6 H_{12}O_6 + 6O_2\rightarrow 6CO_2 + 6H_2O + ATP

In neither of the two processes, carbon dioxide is splitted.

I will give brainiest! PLEASE ANSWER ASAP.How does the law of conservation of mass apply to this reaction: C2H4 + 3O2 → 2H2O + 2
blondinia [14]
<h3>Answer:</h3>

The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

<h3>Explanation:</h3>

<u>We are given;</u>

  • The equation;

C₂H₄ + 3O₂ → 2H₂O + 2CO₂

We need to ask ourselves the following questions;

Is the equation balanced?

  • Yes, the equation because the number of atoms of each element is equal on both sides of the equation.
  • That is; Reactants: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen atoms.
  • Products: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen

What is the law of conservation of mass?

  • According to the law of conservation of mass, the mass of reactants should always be equal to the mass of the products in chemical reactions.

What makes the equation obey the law of conservation of mass?

  • For an equation to obey the law of conservation of mass, it must be balanced.
  • In this case, <u>the equation given is already balanced and therefore obeys the law of conservation of mass</u>.
