What else can I help you with?
What happens if the hydrogen pumps in photosystems 1 and 2 are not working correctly?
The chloroplast will not produce ATP or NADPH.
What would happen if the hydrogen ion pumps in the tiger's mitochondria stopped functioning?
If the hydrogen ion pumps in a tiger's mitochondria stopped functioning, it would disrupt the electron transport chain and the production of ATP through oxidative phosphorylation. This would lead to a decrease in cellular energy production, affecting the tiger's ability to carry out essential functions and potentially resulting in cellular damage and dysfunction.
Why does fadh2 produce fewer ATP molecules than nadh?
NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.
The primary role of oxygen in cellular respiration is to?
EntryWhen a person inhales, oxygen contained in air enters the body through the nose and the mouth.Path to the LungsOxygen-rich air travels through the upper and lower respiratory tracts into the lungs.AlveoliIn the tiniest branches of the lungs, the alveoli remove carbon dioxide and prepare oxygen for transport into the circulatory system.DiffusionOxygen transfers through diffusion from the alveoli to the capillaries. Diffusion is the process of particles of liquids, gases or solids moving from an area of higher concentration to an area of lower concentration.CapillariesThe capillaries connect to the larger blood vessels, which transport oxygen-rich blood to the heart.HeartThe heart pumps oxygen-rich blood to the rest of the body through the circulatory system. All of the cells in the human body use oxygen from the blood to break down glucose for energy.
What is a necessary reactant for cellular respiration to occur?
Oxygen is needed for the Electron Transport Chain, or ETC for short. Oxygen's role in ETC is as the final acceptor of electrons. The transfer of electrons pumps hydrogen protons across the inner mitochondrial membrane through ATP Synthase and this gradient is used to synthesize energy in the form of ATP. This step produces around 30 ATP, this being the most out of all of the three steps of cellular respiration.
Where does the first electron carrier pump hydrogen ions?
The first electron carrier that pumps hydrogen ions during cellular respiration is NADH dehydrogenase (complex I) in the electron transport chain. It pumps hydrogen ions across the inner mitochondrial membrane from the matrix to the intermembrane space.
In mitochondria the electron transport chain pumps protons from the matrix into the intermembrane space whereas in chloroplasts the electron transport chain pumps protons from?
In chloroplasts, the electron transport chain pumps protons from the stroma into the thylakoid lumen. This creates a proton gradient across the thylakoid membrane, similar to the proton gradient established in mitochondria. The energy from this gradient is then used to synthesize ATP through ATP synthase during the process of photophosphorylation.
What are cytochrome carriers?
they are part of the electron transport chain and they are involved with the pumps that create the concentration gradient of H+
What hydrogen pumps move hydrogen ions into which structure?
Hydrogen ions (protons) are primarily moved into the mitochondria by the proton pumps of the electron transport chain, specifically complexes I, III, and IV. These pumps transport protons from the mitochondrial matrix into the intermembrane space, creating a proton gradient. This gradient is essential for ATP synthesis, as protons flow back into the matrix through ATP synthase, driving the conversion of ADP to ATP.
What stage of aerobic cellular respiration pumps hydrogen into the intermembrane compartment?
The stage of aerobic cellular respiration that pumps hydrogen ions into the intermembrane compartment is the electron transport chain (ETC). During this stage, electrons are transferred through a series of protein complexes, leading to the active transport of hydrogen ions from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is essential for ATP synthesis during chemiosmosis.
What happens if the hydrogen pumps in photo systems i and ii and not working correctly?
If the hydrogen pumps in photosystems I and II are not working correctly, there will be a disruption in the electron transport chain of photosynthesis. This will lead to a decrease in the production of ATP and NADPH, which are necessary for the light-dependent reactions to occur. As a result, the overall process of photosynthesis will be impaired, leading to reduced plant growth and metabolism.
Give an example of active transport?
Hydrogen (H+) pumps.
What is the final electron receptor in cellular respiration?
oxygen is used to pull electrons down to the Electron Transport Chain which pumps H+ to create H+ gradient :)
What would happen to the dog if the hydrogen ion pumps in its mitochondria stopped functioning?
If the hydrogen ion pumps in a dog's mitochondria stopped functioning, it would disrupt the electron transport chain, leading to a decrease in ATP production. This could result in decreased energy levels, impaired cellular function, and potentially organ failure if severe and left untreated.
What happens if the hydrogen pumps in photosystems 1 and 2 are not working correctly?
The chloroplast will not produce ATP or NADPH.
Which type of cell transport is used by mitochondria to make hydrogen ions move against their concentration gradient?
Mitochondria utilize active transport to move hydrogen ions (protons) against their concentration gradient. This process primarily occurs during oxidative phosphorylation, where the electron transport chain pumps protons from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is subsequently used by ATP synthase to generate ATP as protons flow back into the matrix.
How does the electron transport chain active during the Krebs cycle affect the hydrogen ion concentration in a mitochondrion?
During the Krebs cycle, the electron transport chain (ETC) actively pumps hydrogen ions (H⁺) from the mitochondrial matrix into the intermembrane space. This process creates a proton gradient, as the concentration of H⁺ ions becomes higher outside the matrix compared to inside. This electrochemical gradient is crucial for ATP synthesis, as H⁺ ions flow back into the matrix through ATP synthase, driving the production of ATP. Thus, the ETC indirectly regulates hydrogen ion concentration, contributing to the overall energy production in the mitochondrion.
