How much ATP does this cost the cell if it uses transport proteins?
The cost of ATP for a cell using transport proteins depends on the type of transport mechanism employed. For active transport, which moves substances against their concentration gradient, the process typically requires the hydrolysis of one ATP molecule per transport cycle. In contrast, facilitated diffusion through transport proteins does not require ATP, as it occurs along the concentration gradient. Therefore, if active transport is utilized, it costs the cell one ATP per transport event.
What does the electron transport chain do?
Produce ATP using energy of NADH2 and FADH2
Synthesis of ATP by chemiosmotic mechanism occurs during?
Synthesis of ATP by chemiosmotic mechanism occurs during oxidative phosphorylation in the inner mitochondrial membrane. Protons are pumped across the membrane by the electron transport chain, creating a proton gradient. ATP synthase then uses this gradient to generate ATP from ADP and inorganic phosphate.
What doesn't produce ATP?
ATP is not produced by passive transport processes like diffusion or osmosis. It is also not directly produced by light energy, but rather by the process of photosynthesis in plants using light energy. Additionally, ATP is not produced by the electron transport chain in anaerobic respiration.
Fermentation in yeast can produce ATP from sugar anaerobically without using any?
Fermentation releases energy without using oxygen
Are symporters active or passive in their transport mechanism?
Symporters are active transport mechanisms that move molecules across a cell membrane using energy from ATP or an electrochemical gradient.

The energy required for the mechanism of active transport comes from?
The product of ATP decomposition.
How does a cell use active transport?
By using ATP.
What is the basic mechanism by which ATP synthase generates ATP in the mitochondria?
The proton gradient set up by the electron transport chain causes mechanical rotation of ATP synthase, and this energy is used to form ATP
What does the electron transport chain transport?
Produce ATP using energy of NADH2 and FADH2
What does the electron transport chain do?
Produce ATP using energy of NADH2 and FADH2
Describe the mechanism behind active transport?
The molecule or ion cross the membrane with the energy provided by ATP as it moves up the concentration gradient.
Synthesis of ATP by chemiosmotic mechanism occurs during?
Synthesis of ATP by chemiosmotic mechanism occurs during oxidative phosphorylation in the inner mitochondrial membrane. Protons are pumped across the membrane by the electron transport chain, creating a proton gradient. ATP synthase then uses this gradient to generate ATP from ADP and inorganic phosphate.
What mechanism is most likely used for the uptake of glucose by an intestinal cell located near the end of the intestinal tract?
active, ATP-fueled transport
During which stage of complete celluar resperation is most of the atp produced?
Most of the ATP is produced during the electron transport chain stage of cellular respiration. This is where the majority of ATP molecules are generated through oxidative phosphorylation using energy released from the transfer of electrons along the electron transport chain.
