Order the steps through which atp synthesis occurs during the light-dependent reactions of photosynthesis in plants. the concentration of hydrogen ions in the thylakoid space increases. electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space. atp synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make atp. hydrogen ions diffuse across the thylakoid membrane into the stroma through atp synthase. energy from the sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions. ↓ ↓ ↓ ↓ reset next

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
