which statement best describes the process of respiration
a
using carbon dioxide and oxygen by plant cells to make carbohydrates.
b
use food energy by all cells to produce cell energy in order to do work.
c
ATP used to create complete organic molecules used in growth and development.
d
use light energy by all cells to produce food.
b
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:
b. Use food energy by all cells to produce cell energy in order to do work.
Respiration is the process by which living organisms convert glucose and oxygen into energy, carbon dioxide, and water. It is the process through which cells obtain the energy they need to perform various functions and activities. This process involves breaking down food molecules through a series of chemical reactions to release energy in the form of ATP (adenosine triphosphate), which is utilized by cells for various cellular processes and functions.
The statement that best describes the process of respiration is option B: "Use food energy by all cells to produce cell energy in order to do work."
Explanation:
Respiration is a cellular metabolic process that occurs in all living organisms, including plants and animals. It involves the breakdown of food molecules, such as glucose, to release energy in the form of ATP (adenosine triphosphate). This energy is then used by cells to perform various functions and carry out work.
Option A, "Using carbon dioxide and oxygen by plant cells to make carbohydrates," describes the process of photosynthesis, not respiration. Photosynthesis is the process by which plants convert carbon dioxide and sunlight into glucose (carbohydrates), using oxygen as a byproduct.
Option C, "ATP used to create complete organic molecules used in growth and development," does not accurately describe respiration. While ATP is indeed used in various cellular processes related to growth and development, the primary purpose of respiration is to generate ATP, not to create complete organic molecules.
Option D, "Use light energy by all cells to produce food," is also incorrect. The process described here is again photosynthesis, not respiration. Only certain cells, such as the cells in the chloroplasts of plants, are capable of using light energy to produce food molecules through photosynthesis. Respiration, on the other hand, occurs in all cells and does not require light energy.
