What else can I help you with?
Where do we find ions gradients in cell membranes?
Gradiend occurs between two places. Mainly either sides of membrane
What gas diffuses through cell membranes so that respiration can take place?
oxygen
What are osmotic gradients?
When water flows from areas of high concentration to areas of low concentration through semi-permeable membranes; down it'd concentration gradient.
Why mitochondria have folded inner membranes?
Foldings increases surface area.So respiration can be done efficiently.
What part of respiration produces ATP?
Oxidative phosphorylation (contrast substrate-level phosphorylation) is the process of ATP generation during aerobic cellular respiration. It is accomplished through a process of chemiosmosis, wherein H+ ions are concentrated on one side of mtichondrial membranes, creating an electrochemical gradient which is equilibrated when hydrogen ions (protons) pass through the enzyme ATP synthase, resulting in rotation of the protein and phosphorylation of ADP to ATP.
Generation of proton gradients across membranes occur during?
Generation of proton gradients across membranes occurs?
Generation of proton gradients across membranes occurs during what?
Generation of proton gradients across membranes occurs during cellular respiration in the electron transport chain. This process involves the movement of electrons through a series of protein complexes, which pump protons across the inner mitochondrial membrane, creating a proton gradient that is used to generate ATP through ATP synthase.
How do cells maintain homeostasis by utilizing the chemical and electrical gradients across their membranes?
Cells maintain homeostasis by utilizing chemical and electrical gradients across their membranes. This process involves the movement of ions and molecules in and out of the cell to regulate internal conditions and ensure proper functioning.

How are potassium and sodium transported across plasma membranes against the?
Potassium and sodium are transported across plasma membranes against their concentration gradients through the action of specific ion pumps such as the sodium-potassium pump. This pump uses energy from ATP to actively transport three sodium ions out of the cell and two potassium ions into the cell for every cycle. This process helps maintain the electrochemical gradients necessary for cell function.
In eukaryotic cells the cell organelle that is surrounded be two membranes and that is the site of cellular respiration which produces ATP?
Mitochondria
Is energy used to move ions an molecules across membranes in your nerves and kidneys?
Yes, energy is required to move ions and molecules across membranes in nerves and kidneys. Most commonly, this energy comes from ATP hydrolysis, which provides the necessary energy for active transport processes such as ion pumps, co-transporters, and exchangers to move substances against their concentration gradients. This process is essential for maintaining proper ion gradients and overall cellular function.
How do electrical and chemical gradients contribute to the movement of ions across cell membranes?
Electrical and chemical gradients play a crucial role in the movement of ions across cell membranes. The electrical gradient is created by differences in charge between the inside and outside of the cell, while the chemical gradient is formed by variations in ion concentrations. These gradients drive ions to move from areas of high concentration to low concentration, a process known as passive transport. Additionally, ion channels and transport proteins in the cell membrane facilitate the movement of ions across the membrane, allowing for the maintenance of proper ion balance within the cell.
Where in a plant does respiration occur?
Respiration in plants occurs in the mitochondria of cells, particularly in the cytoplasm and in the inner membranes of the mitochondria. During respiration, glucose is broken down to release energy in the form of ATP, which is crucial for the plant's metabolic processes.
