Anna is working on the study guide for her biology semester exam. the statement is made that atp is required for all cellular functions. anna is not sure this is true, so she starts generating a list of cellular processes she has studied this semester. she sorts them by processes that require atp and those that do not. she concludes that while atp is required for cellular processes requiring energy input, atp is not a requirement of all cellular processes.

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.
