What DCMU inhibits electron transport in chloroplast by preventing the reduction?
DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) inhibits electron transport in chloroplasts by blocking the plastoquinone binding site in photosystem II. This prevents the reduction of plastoquinone and disrupts the flow of electrons in the photosynthetic electron transport chain. As a result, the light-dependent reactions of photosynthesis are impaired, leading to decreased ATP and NADPH production. Consequently, this inhibition affects overall photosynthetic efficiency and plant growth.
What happens in a mitochondrion?
In a mitochondrion, cellular respiration occurs, where glucose and oxygen are converted into energy in the form of ATP. This process involves the citric acid cycle and the electron transport chain. Mitochondria are known as the powerhouse of the cell due to their role in generating energy for cellular activities.
How does malonate inhibit NADH?
Malonate inhibits NADH by competing with NAD+ for binding to the active site of enzyme NADH dehydrogenase within the electron transport chain. This competition prevents NADH from donating electrons to the enzyme, disrupting the flow of electrons and inhibiting ATP production.
The granules of the inner membrane of the mitochondrion are believed to be the site of chemical reaction that produce?
The granules of the inner membrane of the mitochondrion are believed to be the site of chemical reactions that produce ATP, which is the primary energy currency of the cell. These reactions are part of the electron transport chain and oxidative phosphorylation processes that generate ATP through the process of cellular respiration.
What is the function of the thylakoids in a chloroplast?
Thylakoids are membrane-bound compartments inside chloroplasts where photosynthesis takes place. They contain chlorophyll and other pigments that capture light energy to drive the reactions of photosynthesis, converting light energy into chemical energy. They also house the protein complexes involved in the electron transport chain that generates ATP and NADPH for the Calvin cycle.
What is the electron chain?
The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. Easy huh?
When is the electron transport chain carried out?
Plants, fungi, and animals are all eukaryotes and possess mitochondria, which is the site of the electron transport chain. Prokaryotes have no mitochondria and perform the electron transport chain across their cell membranes. Electron transport chain also occurs in thylakoid membrane of chloroplasts.
Where does a Electron Transport Chain happen?
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
Where is the site of the electron transport system?
mitochondrial inner membrane (cristae)
Where do electrons from the Krebs cycle go next?
Electron Transport The point of the kreb's cycle is to create energy. The energy made is in the form of ATP (Adenosinetriphosphate) which the body uses immediatley or is in the form of electrons carried by NADH or FADH2. These then go on to the electron transport chain where more molecules of ATP are created.
What DCMU inhibits electron transport in chloroplast by preventing the reduction?
DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) inhibits electron transport in chloroplasts by blocking the plastoquinone binding site in photosystem II.

Consequently, this inhibition affects overall photosynthetic efficiency and plant growth.
Site of aerobic respiration in cells?
The site of aerobic respiration in cells is the mitochondria. This is where glucose is broken down in the presence of oxygen to produce energy in the form of adenosine triphosphate (ATP).
In a cell the site of oxygen utilization is the?
The site of oxygen utilization in a cell is the mitochondria. Within the mitochondria, oxygen is used in the process of cellular respiration to generate energy in the form of ATP through the electron transport chain and oxidative phosphorylation.
What is the difference between substrate level phosphorylation and chemiosmosis?
substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.
Where is the electron transport system found on the bacteria?
Since prokaryotic cells do not have complex organelles such as a nucleus or mitochondria as do their counterparts, the eukaryotic cells. The electron transport system (ETS) for bacteria is found on the inner membrane.
In cellular respiration the most energy is transferred into ATP during what?
During the electron transport chain, which is the site of oxidative phosphorylation. This involves the transfer of electrons from donors to acceptors (such as oxygen). This is a very efficient process for the production of ATP (the form of energy used by cells).
What happens in a mitochondrion?
In a mitochondrion, cellular respiration occurs, where glucose and oxygen are converted into energy in the form of ATP. This process involves the citric acid cycle and the electron transport chain. Mitochondria are known as the powerhouse of the cell due to their role in generating energy for cellular activities.
