<h3>Chain of electron transfer The electron transport chain is the final stage of the respiration route, and it is where the most ATP molecules are produced. The electron transport chain is a group of proteins located on mitochondria's inner membrane. The hydrogen ions and electrons are released into the transport chain by NADH.</h3>
An electron transport chain (ETC) is a collection of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occur at the same time) and couple this electron transfer with proton (H+ ion) transfer across a membrane. The electron transport chain contains many membrane-bound enzymes.
The reference point = a object used for comparison to determine if something is in motion.
An object is in motion if it changes position relative to a reference point.
You assume that the reference point is stationary, or not moving.
Answer:
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
