Cells transport molecules without using energy through three primary methods: diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of higher concentration to one of lower concentration until equilibrium is reached. Facilitated diffusion utilizes specific transport proteins in the cell membrane to help polar or charged molecules cross the membrane along their concentration gradient. Osmosis specifically refers to the movement of water across a semipermeable membrane, also driven by concentration gradients.
Of the three, water will move easily. The others require help and therefore the use of energy.
Transporting oxygen and nutrients to cells throughout the body, providing energy and essential building blocks for cellular function. Removing waste and carbon dioxide from cells, maintaining proper pH levels and preventing toxic buildup. Facilitating communication between different organs and tissues by transporting hormones and signaling molecules.

Yes, glycerol is a component of fat molecules known as triglycerides. Triglycerides consist of a glycerol molecule attached to three fatty acid molecules. Glycerol provides the backbone structure for storing and transporting fats in the body.

Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
Molecules moving with kinetic energy can collide with other molecules or surfaces, transfer energy to other molecules through collisions, and change direction due to interactions with other molecules in their environment.

Yes. Every living thing on earth requires those three things. I just finished learning about that in class about a month and a half ago
The three molucules are carbon, hydrogen and oxigen.
Three-carbon molecules of phosphoglycerate (PGA) are converted to energy-rich glyceraldehyde-3-phosphate (G3P) sugar molecules through the process of photosynthesis, specifically during the Calvin cycle. This conversion requires the input of energy from sunlight and enzymes that catalyze the chemical reactions involved in the process.

The three main types of molecules in food that provide us with energy are carbohydrates, proteins, and fats. Carbohydrates are the body's preferred source of energy, while proteins and fats play important roles in energy production and storage.

ATP molecules, carbohydrates (such as glucose), and lipids (such as fats) store energy in chemical bonds.
The three phase changes that require energy to be removed are condensation, freezing, and deposition. During condensation, gas transitions to liquid, releasing energy. Freezing occurs when a liquid changes to a solid, also releasing energy. Deposition is the direct transition from gas to solid, which releases energy as well.
