What organism uses energy for everything they do?
All living organisms, including bacteria, plants, animals, and humans, require energy to carry out their cellular functions, such as growth, reproduction, and movement. This energy is obtained through processes like photosynthesis, cellular respiration, or other metabolic pathways.
Carbon skeletons to be broken down during cellular respiration can be obtained from?
Carbon skeletons for cellular respiration can be obtained from glucose, fatty acids, and amino acids. These molecules are broken down in different metabolic pathways to generate energy in the form of ATP.
Can other molecules besides glucose be used in cellular respiration?
Yes, other molecules besides glucose can be used in cellular respiration. Fatty acids and amino acids can also be broken down in specific pathways to generate ATP through cellular respiration. Each type of molecule enters cellular respiration at different points in the metabolic pathway.
All organisms get energy they need to regenerate ATP from?
All organisms obtain the energy they need to regenerate ATP from breaking down organic molecules through processes such as cellular respiration or fermentation. This energy is stored in the chemical bonds of molecules like glucose, which are then converted into ATP through metabolic pathways.
What statement is true about catabolic pathways?
Catabolic pathways involve breaking down complex molecules into simpler ones to release energy. These pathways are responsible for providing organisms with the energy needed for various cellular processes.
What is the major adaptive advantage for cellular respiration?
Since some organisms are able to switch metabolic pathways depending on if oxygen is available they have an adaptive advantage. For other organisms if there is no oxygen then there is no respiration.
What does cellular respiration do to benefit organism?
Cellular respiration is the process by which organisms convert glucose into energy (ATP) to fuel cellular activities. This energy is essential for various biological processes, such as growth, movement, and reproduction. Ultimately, cellular respiration is vital for an organism's survival and overall function.
What are pathways of cellular respiration?
Glycolysis and Fermentation (Lactic Acid and Alcoholic).
What are all the pathways in cellular respiration?
glycosis, krebs, and electron transformation
What type of organisms are capable of cellular respiration?
Organisms that have cells with mitochondria are capable of cellular respiration. This includes most eukaryotic organisms, such as plants, animals, fungi, and protists. Anaerobic organisms that lack mitochondria, like some bacteria, use alternate pathways for energy production.
What are the main purposes of both photosynthesis and cellular respiration?
The main purpose of photosynthesis is to generate carbohydrates from atmospheric CO2. The main contribution of photosynthesis is the liberation of O2 back to the atmosphere.The central purpose of cellular respiration is the production of ATP molecules that are necessary for the most metabolic pathways in organisms. The secondary product of cellular respiration is a molecule of H2O.
Why do all organisms respire?
All organisms respire to convert biochemical energy from nutrients into adenosine triphosphate (ATP), which is essential for powering cellular processes. Respiration allows for the efficient extraction of energy from food, enabling growth, reproduction, and maintenance of cellular functions. Additionally, respiration helps regulate metabolic pathways and supports the overall homeostasis of the organism. Without respiration, cells would lack the energy needed for survival.
What features of the photosynthesis and cellular respiration biochemical pathways are reverse of one another and which parts are not?
Features that are reverse of one another: In photosynthesis, carbon dioxide is converted into glucose, while in cellular respiration, glucose is broken down to produce carbon dioxide. Photosynthesis produces oxygen as a byproduct, whereas cellular respiration consumes oxygen as a reactant. Features that are not reverse: Both pathways involve the use of electron transport chains to generate ATP. Both pathways occur in specialized organelles - photosynthesis occurs in the chloroplasts, while cellular respiration occurs in the mitochondria.
What mineral ion is important in cellular respiration?
The mineral ion important in cellular respiration is calcium. It plays a crucial role in activating enzymes involved in the metabolic pathways of cellular respiration. Calcium helps regulate various steps in the process, particularly in the release of energy stored in glucose.
What organism uses energy for everything they do?
All living organisms, including bacteria, plants, animals, and humans, require energy to carry out their cellular functions, such as growth, reproduction, and movement. This energy is obtained through processes like photosynthesis, cellular respiration, or other metabolic pathways.
What happens to oxygen during aerodic respiration?
Oxygen was utilized by cellular pathways and they will be at the end converted to Carbondioxide as a waste product.
What does cellular respiration take in?
Cellular respiration requires a macromolecule to be broken down (usually glucose) and a final electron acceptor for the end of the electron transport chain (usually oxygen in most organisms). The reactants are a product of photosynthesis.
