which statement best describes the process of respiration?
a
using carbon dioxide and oxygen by plant cells to make carbohydrates.
b
ATP used to create complete organic molecules used in growth and development.
c
use light energy by all cells to produce food.
d
use food energy by all cells to produce cell energy in order to do work.
d
use food energy by all cells to produce cell energy in order to do work.
The statement that best describes the process of respiration is:
d
Use food energy by all cells to produce cell energy in order to do work.
The correct answer is "d) Use food energy by all cells to produce cell energy in order to do work."
Respiration is the process by which living organisms convert food into energy that cells can use to perform various functions and tasks. It involves breaking down organic molecules, such as glucose, in the presence of oxygen to release energy in the form of ATP (adenosine triphosphate). Let me explain how to arrive at this answer:
Option a) states that respiration involves using carbon dioxide and oxygen by plant cells to make carbohydrates. While plants do use carbon dioxide and oxygen during photosynthesis to produce carbohydrates, respiration is a separate process that occurs in all cells, not just in plant cells.
Option b) suggests that ATP is used to create complete organic molecules used in growth and development. While ATP is indeed involved in many cellular processes, including growth and development, it is actually produced during respiration, not used to create organic molecules.
Option c) states that respiration uses light energy by all cells to produce food. This is incorrect, as respiration is a process that occurs in the absence of light. In contrast, the process described here is actually photosynthesis, where plants use light energy to produce food.
Option d) correctly describes respiration as the process of using food energy by all cells to produce cell energy in order to do work. This is the process by which cells extract energy from the breakdown of glucose or other organic molecules and convert it into ATP, which is then utilized for various cellular activities.
Therefore, the best description of the process of respiration is option d) "Use food energy by all cells to produce cell energy in order to do work."
