Could cellular respiration work without photosynthesis?
Yes, and it does all the time, but some other energy source is required. For one thing, all animal cells undergo cellular respiration without photosynthesis, as do all anaerobic bacteria (yeasts, etc.), and many plants and animals that grow on thermal vents on the bottom of the ocean. Instead of getting energy from light, they use chemical energy (animals and yeasts) or geothermal (heat) energy, such as in the case of aquatic organisms on heat vents.
Why is phosphorus important in cellular respiration?
Phosphorus is important in cellular respiration because it is a key component of ATP (adenosine triphosphate), which is the primary energy currency in cells. During cellular respiration, ATP is produced through processes like glycolysis, the citric acid cycle, and oxidative phosphorylation, where phosphorus is essential for the synthesis and transfer of energy within the cell.
What is a product if cellular respiration and not fermentation?
The end products of cellular respiration are carbon dioxide, water, and ATP (adenosine triphosphate). These products are generated through the breakdown of glucose and other organic molecules in the presence of oxygen in the mitochondria of the cell. Fermentation, on the other hand, produces end products such as alcohol or lactic acid in the absence of oxygen.
How are the photosynthesis and cellular respiration equations related?
photosynthesis equation is H2O+Co2->(ATP+) C6H2O6+O2 cellular reapiratation is O2+C6H2O(-> ATP)+Co2+H2O. so photoshynthesis eqaution backwards is celluar respirations equation. and they also have all the same stuff in them (water, carbon, energy, glucose, and oxygen.)
What can increase the rate of cellular respiration?
Enzymes, which act as catalyst, speed up the rate of metabolic reactions.
Which one of the reactant for cellular respiration gets oxidized and which one gets reduced?
During cellular respiration, glucose gets oxidized to form carbon dioxide and water, while oxygen gets reduced to form water. Glucose loses electrons and hydrogen atoms, which are transferred to oxygen during the process, resulting in the reduction of oxygen to water.
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.
Oxygen and Carbon Dioxide
How are the products of cellular respiration and the starting products of photosynthesis related?
The products of cellular respiration (carbon dioxide and water) are the starting products of photosynthesis. In photosynthesis, carbon dioxide and water are used to produce glucose and oxygen, which are then used in cellular respiration to produce energy. This interdependence forms a continuous cycle between the two processes.
What is the correct sequence stages in cellular respiration?
The correct sequence of stages in cellular respiration is glycolysis, Krebs cycle and then electron transport chain. However, this will depend on whether the respiration is anaerobic or aerobic.
What is organelle that carry out cellular Respiration an photosynthesis?
Cellular respiration and photosynthesis are processes carried out in separate organelles within the cell. Cellular respiration occurs within mitochondria present in all living cells - both plant and animal. Photosynthesis occurs within the chloroplasts of plant cells only.
How are photosynthesis and cellular respiration related in terms of energy transformation?
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
The net process of photosynthesis is described by the following equation:
6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2
Which energy molecule is produced as a result of a cellular respiration?
Adenosine triphosphate (ATP) is the energy molecule produced as a result of cellular respiration. ATP is the primary energy carrier in most living organisms and is generated through the process of breaking down glucose molecules in the presence of oxygen.
How are the equations for photosynthesis and cellular respiration different?
The overall equation of photosynthesis differs from the reverse of the overall equation of cellular respiration in that sunlight is not needed in the reverse of cellular respiration. Also, chlorophyll need not be present for the latter process.
How is dehydrogenase involved in the reduction of coenzyme NADH during cellular respiration?
Dehydrogenase enzymes catalyze the removal of hydrogen atoms from molecules like NADH during cellular respiration. This process results in the oxidation and reduction of substrates, allowing the energy released to be used to make ATP. The reduced coenzyme NADH carries the electrons to the electron transport chain to produce ATP in aerobic cellular respiration.
What is location of ETC and chemiosmosis in photosynthesis and cellular respiration?
In photosynthesis, ETC and chemiosmosis occur in the thylakoid membranes of chloroplasts. In cellular respiration, these processes take place in the inner mitochondrial membrane. These locations are where the electron transport chain (ETC) pumps protons across the membrane, creating a proton gradient that drives ATP production through chemiosmosis.
Both fermentation and cellular respiration result in end products that contain C-H bonds. In cellular respiration, glucose is broken down to produce ATP, CO2, and H2O, all of which contain C-H bonds. In fermentation, depending on the type, end products such as ethanol or lactic acid are produced, and these also contain C-H bonds.
What could account to the different cellular responses to histamine?
The differential cellular responses to histamine can be attributed to variations in histamine receptor distribution across tissues. Additionally, differences in signal transduction pathways and downstream effector molecules in different cell types can lead to varying responses to histamine. Lastly, the presence of other mediators or cytokines in the tissue microenvironment can modulate the cellular response to histamine.
What two things do animals cells convert into energy during cellular respiration?
They convert Oxygen and Sugar into energy and waste products (Water and Carbon Dioxide).
What stages of cellular respiration involve cytochromes?
Cytochromes are involved in electron transport chain, specifically in the complexes III and IV stages of cellular respiration. In complex III, cytochrome b and cytochrome c are key components, while in complex IV, cytochrome c oxidase plays a crucial role in the final transfer of electrons to oxygen.
Autotrophs are organisms that can perform photosynthesis to produce their own food using sunlight, while heterotrophs cannot perform photosynthesis and rely on consuming other organisms for food. Both autotrophs and heterotrophs perform cellular respiration to convert organic compounds into energy, regardless of their ability to photosynthesize.
What common between respiration photosynthesis and lithrotropic energy generation?
All three processes involve the conversion of energy. Respiration and lithotrophic energy generation involve the breakdown of organic or inorganic compounds to produce energy, whereas photosynthesis involves the conversion of light energy into chemical energy. Additionally, all three processes are vital for the survival of organisms and play key roles in the global carbon cycle.
Photosynthesis and cellular respiration are part of which cycle?
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
What does cellular activity do during the phases of Eccentric contraction?
During the eccentric contraction phase, cellular activity involves lengthening the muscle fibers while generating force. This phase creates tension in the muscle as it elongates, allowing for controlled movement and resistance against external forces. Additionally, cellular processes such as protein breakdown and remodeling contribute to muscle adaptation and strength gains.
