Question

Cellular respiration is the process that converts nutrients into ATP (adenosine triphosphate), a storage molecule that
provides energy for the cell. Which statement is true about cellular respiration?
a.Cellular respiration is observed only in heterotrophs.
B.Plants perform photosynthesis and cellular respiration.
C.All stages of cellular respiration require oxygen.
d.Cells need to take in carbon dioxide to perform cellular respiration.

Answer 1

Answer:

The answer is B.

Explanation:

A is incorrect because B is correct (plants are autotrophs).

C is incorrect because the first stage of cellular respiration is glycolysis, and the second is the Krebs cycle, neither of which require oxygen.

D is incorrect because cells take in oxygen to perform cellular respiration. Carbon dioxide is the product.

Answer 2

Answer:

B. Plants perform photosynthesis and cellular respiration.

Explanation:

Cellular respiration is used by most living beings to obtain vital energy for their survival.

It can take place through the aerobic process, which uses the oxygen present in the environment. But it can also occur anaerobically, when oxygen does not participate.

Also in anaerobic respiration, fermentation can occur, which gives rise to yogurt and alcoholic beverages.

Although it is performed by all living beings, only plants perform photosynthesis and cellular respiration.

Although it is a very complex process, cellular respiration is done through various chemical reactions, we can simplify it. A summary can be made in the following equation: C6H12O6 + 6 O2 ⇒ 6 CO2 + 6 H2O + Energy
