Answer:
cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement
<span>Hydrogenous sediments originate from elements in seawater. </span><span>Hydrogenous sediments are formed by precipitation of minerals from the ocean’s water or can be formed as a new mineral as a result of chemical reactions between the water of the ocean and sediments that already exist on the ocean floor. </span>
Answer:
The electron transport chain (ETC) is located in the mitochodrial cristae. As electrons move from one protein complex to the other via redox reaction, energy is used to pump hydrogen ions (H+) from the matrix to the intermembrane space of the mitochondria. As hydrogen ions flow down the concentration gradient from the intermembrane space to the mitochodrial matrix, ATP is synthesized by the enzyme ATP synthase.
The ATP synthase complex can be compared to the gates of a dam. when the gates of a hydroelectric dam are opened, water rushes through, and electricity (energy) is produced. Similarly, when H+ ions flow down a gradient from intermembrane space into the matrix, the enzyme ATP synthase synthesizes ATP from ADP and inorganic phosphate or P<em>i. </em>This process is called chemiosmosis because ATP production is linked with the establishment of a proton (H+) gradient across the membranes.
