Where glucose is broken down into smaller molecules to produce energy. The second part of the process takes place in the
slavikrds [6]

Answer:

Mitochondria

Explanation:

Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.

The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of  3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.

In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.

How many water molecules are produced when 5.2g O2 are reacted
gtnhenbr [62]

Answer:

Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.

Explanation:

By the reaction

H2+ 1/2 O2 → H2O

Moles of O2 = 5.2\32

⇒1 mole of O2 produce 1  mole of H2O

  1 mole O2 will produce 2 mole  of H2O

Therefore, 5.2\32 mole will produce {2}\times{\frac{5.2}\times{32}}

⇒ Molecules of H2O  will be

         {2}\times{\frac{5.2}{32}} = \frac{x}{{6.02}\times{10^23}}

= 1.956×10^22 moleculesof H2O.

Pls help this is due in 5 mins!!!! Brainlest to the best answer and 20 points
Ivan

Answer:

Your pulse will go higher or lower, This explains the changes in our pulse rate because, our heart is having to work twice as hard. Our heart is having to work twice as hard because while its producing oxygen its also getting rid of the Carbon Dioxide. while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse. on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse

In the bronsted-lowry acid-base definition, an acid is a molecule (or ion) that _____ a proton and a base is a molecule (or ion)
agasfer [191]

In the Bronsted-Lowry acid-base definition, an acid is a molecule (or ion) that donates a proton and a base is a molecule (or ion) that accepts a proton.

Bronsted-Lowry theory of acid and bases took the Arrhenius definition one step further, as a substance no longer needed to be composed of hydrogen (H+) or hydroxide (OH-) ions in order to be classified as an acid or base. For example , consider the following chemical equation:

HCl (aq) +NH₃ (aq) → NH⁺₄ (aq) + Cl⁻(aq)

Here, hydrochloric acid (HCl) "donates" a proton (H+) to ammonia (NH3) which "accepts" it , forming a positively charged ammonium ion (NH4⁺) and a negatively charged chloride ion (Cl⁻). Therefore, HCl is a Bronsted-Lowry acid (donates a proton) while the ammonia is a Bronsted-Lowry base (accepts a proton). Also, Cl⁻ is called the conjugate base of the acid HCl and NH4⁺ is called the conjugate acid of the base NH3.

A Bronsted-Lowry acid is a proton (hydrogen ion) donor.

A Bronsted-Lowry base is a proton (hydrogen ion) acceptor.

In this theory, an acid is a substance that can release a proton (like in the Arrhenius theory) and a base is a substance that can accept a proton.

Why is the atomic radius of sodium much smaller than the atomic radius of potassium
