How does cellular respiration demonstrate the conservation of mass?

Biology

Nonamiya [84]3 years ago
5 0

Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:

C6H1206 + 6O2 ---- 6CO2 + 6H2O

Th number of atoms of reactants equals the number of atoms of products:

six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms

No atoms are created or destroyed in this process, they're just rearranged into different molecules.

We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.

Answer:

Just like in photosynthesis, the total number of atoms of the starting elements of cellular respiration equals the number of atoms of the ending products.

Hope this helps! :D

An air pressure of 1,005 millibars is equivalent to approximately how many inches of Mercury?
N76 [4]

1005milibars of pressure corresponds to 29.68inches of mercury.

Option D.

<h3><u>Explanation:</u></h3>

Mercury has a density of around 13.6gm/cc. Thus the pressure of inches of mercury will have a huge effect on the value. As far as bar is concerned, it's around the normal atmospheric pressure measured at sea level. Its around 1,00,000 pascals. So from converting a pressure at millibars to inches of mercury, we need to divide the value by a factor of 33.864.

So, pressure in milibars =1005milibars.

So, pressure in inches of mercury = 1005/33.864 = 29.68 inches of mercury.

What function do chloroplasts perform
Scilla [17]

Answer:

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

How would the body most likely respond to the condition illustrated
Mashutka [201]

Answer:

A) Faster blood flow: A faster blood flow means the heart pumps blood with more power. Pumping blood to fast for too long can damage the heart muscle and interfere with its normal electrical signals, which can result in a dangerous heart rhythm disorder.

B) Infection: infection is caused by invasion of the body by external microorganisms. Disease can arise if the host's protective immune mechanisms are compromised and the organism inflicts damage on the host.

C) vomiting: This is an involuntary, forced expulsion of stomach contents usually through the mouth or nose. Body's reaction can be aspiration, electrolyte and water loss, damage to the enamel of the teeth, tear of the esophageal mucosa etc.

D) High blood pressure: This is due to the heart pumping blood at high pressure putting a strain on the walls of the blood vessels. In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs.
