A student claims that cellular respiration is essential to cells so that they have a means for getting rid of excess carbon diox
Phantasy [73]

The correct answer is "Cellular respiration does not consume carbon dioxide".

Cellular respiration refers to the set of chemical reactions by which cell harnessed energy from nutrients and convert it to ATP (also called as energy currency of the cell).

It is essential for the cell as it generates ATP which is used in all the processes such as DNA replication, repair, etc.

Cellular respiration uses oxygen and releases carbon dioxide as a waste product.

Oxygen is provided by air we inhaled and carbon dioxide is released as a part of exhaled air.

The general equation of cellular respiration can be written as:

C_{6}H_{12}O_{6} + 6O_{2}C

→ 6CO_{2} + 6H_{2}O + ATP6CO

Pepsi [2]

Answer:

Almost immediately after injection, you find yourself swept into a good-sized chamber, the left atrium. However, you do not stop in this chamber, but continue to plunge downward into a larger chamber below. You land with a large splash and examine your surroundings. All about you are huge white cords, hanging limply from two flaps of endothelial tissue far above you. You report that you are sitting in the left ventricle chamber of the heart, seeing the flaps of the mitral valve above you. The valve is open and its anchoring cords, the chordae tendineae, are lax. Since this valve is open, you conclude that the heart is in the systole/contraction phase of the cardiac cycle.

Explanation:

Once the oxygenated blood enters the heart through the pulmonary vein, it goes to the left atrium. From there, it goes down to the left ventricle passing through the mitral valve, also known as the bicuspid valve. This valve prevents blood's backflow when the heart contracts, allowing the blood's flow from the ventricle to the aorta.

The chordae tendineae, also known as tendinous cords, are in the mitral and the tricuspid valve. They are cords that are attached to the valve and the heart walls. They are lax during atrial systole, and with the help of blood pressure, they allow the valve to open and welcome the blood into the left ventricle. The tendinous cords are tense during ventricle systole preventing the valve from opening and causing a backflow from the ventricle to the atrium.

What are food enzymes?
Llana [10]

there aren't many enzymes in food, mainly in fruits, the enzymes in friuts are very similar to ptylin found in the mouth that help break down sugar, they do not need to be ingested before they activate, a proof of this is the apple test, buy an apple, take a bite and leave it without covering it for a few minutes, you'll notice that the bitten part starts turning yellowish brown because the enzymes in the apple are already breaking it down.  

In summary, they do not need to be ingested before activation, and the major characteristic of an enzyme is that they do not change after they react with (breakdown) food, so they are in the same form before and after they finish breaking down the food.
