Why is osmosis and diffusion a type of passive transport?
Osmosis and diffusion are considered passive transport because they do not require energy input from the cell. Molecules move from areas of high concentration to low concentration in a random process, which does not require the cell to expend energy.
Organelles breaks down high energy molecules consumes oxygen?
Mitochondria break down high energy molecules like glucose through a process called cellular respiration, which ultimately produces ATP for energy. This process requires oxygen as the final electron acceptor in the electron transport chain.
How are the molecules arranged in gas?
In a gas, molecules are arranged randomly and move freely in all directions. They have high kinetic energy and collisions between molecules are elastic. The distance between molecules is large compared to the size of the molecules themselves.
What material is being referred by energy-rich compound?
Energy-rich compounds refer to molecules that store energy within their chemical bonds. Examples include ATP, which is the primary energy currency of cells, and high-energy phosphate bonds found in molecules like phosphocreatine. These compounds release energy when their bonds are broken during metabolic processes.
What charateristics of molecules move firely and hit one another?
Molecules in a gas have high kinetic energy, causing them to move rapidly and collide with one another. This constant motion and collisions lead to the transfer of energy and momentum between molecules, creating pressure and contributing to the overall behavior of the gas.
Is active transport from high to low concentrations considered a high-energy process?
Yes, active transport from high to low concentrations is considered a high-energy process because it requires energy to move molecules against their concentration gradient.
How does the process of diffusion move molecules from a low concentration to a high concentration, and is this movement considered active or passive?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. This process does not require energy input and is considered passive transport.
Where does energy come from when you eat?
From bonds in high energy molecules.
What high energy molecules made from photosynthesis?
sugar
What best explains why carbohydrates are advertised by manufacturers of candy bars and sports drinks as a quick energy boost?
Carbs are reduced molecules that have high-energy electrons.
What is energy from high temperatures?
High temperature speeds up movement in the molecules. This means with higher temperature, there is more energy
What is the series of special molecules in the mitochondria that receive the high energy electrons from the carriers called?
The electron transport chain is a series of special molecules in the mitochondrion that receives the high-energy electrons from the carriers.
Do solids have molecules with high kinetic energy?
Yes, in solids, molecules vibrate around fixed positions and have relatively low kinetic energy compared to liquids and gases. The kinetic energy of solid molecules is mainly in the form of vibrational energy rather than translational energy.
How do most complex get their energy?
Mitochondria in their cells produce vast amount of high energy molecules ATP.
What group of compounds use only high energy molecules?
A group of compounds that use only high energy molecules are phosphoenolpyruvate (PEP) carboxylase enzymes. These enzymes are involved in pathways like gluconeogenesis where high-energy phosphate bonds are used for the production of glucose from simple precursors.
What organic compound is considered to be a long storage of energy?
Lipids, specifically triglycerides, are considered to be a long-term storage form of energy in organisms. Lipids are highly efficient molecules for storing energy due to their high energy density and low solubility in water.
What are the name of high energy molecules that run the cell's machinery?
adenosine triphoshate
