Cyclosis movements in Elodea cells. Cyclosis movements, also known as cytoplasmic streaming, are the directed flow or movement of the cytoplasm within a cell.
Cyclosis is the active circulation of cytoplasm around the cell, usually driven by interactions between actin filaments (part of the cytoskeleton) and myosin motor proteins.
Cyclosis functions: i) enhances transport of nutrients, metabolites, and signaling molecules; ii) distributes organelles evenly within the cytoplasm; iii) Improves gas exchange and waste removal in large cells; iv) helps maintain homeostasis by mixing cytoplasmic contents.

A simple trick to remember Citric Acid Cycle (Krebs Cycle) 🥰✌️😮

The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
