Internal factors that affect cell division include the cell's genetic material (DNA) and the presence of specific regulatory proteins such as cyclins and cyclin-dependent kinases. External factors include growth factors, nutrient availability, density-dependent inhibition (cell crowding), and environmental conditions such as temperature and pH. Additionally, signaling molecules from neighboring cells can influence the rate of division. Together, these factors ensure that cell division occurs in a controlled and appropriate manner.

What is the internal factors that control metabolism and the external factors?

Internal factors that control metabolism include hormonal regulation, enzyme activity, genetic makeup, and the availability of substrates for metabolic processes. Hormones like insulin and glucagon play crucial roles in regulating glucose and fat metabolism, while enzymes catalyze biochemical reactions. External factors encompass dietary intake, physical activity levels, environmental temperature, and lifestyle choices, all of which can significantly influence metabolic rates and efficiency. Together, these internal and external factors interact to maintain metabolic balance and energy homeostasis in the body.


What are internal and external regulators?

Internal regulators are mechanisms within an organism that control their biological processes, such as hormones that maintain homeostasis. External regulators are environmental factors outside the organism that influence its biological responses, like temperature or availability of nutrients. Both internal and external regulators play key roles in determining an organism's growth and development.
