endocrine glands secrete chemicals directly into the body's tissues through specialized ducts true or false
False. Endocrine glands secrete chemicals called hormones directly into the bloodstream, not through specialized ducts.
These hormones then travel to various tissues and organs throughout the body, where they elicit specific responses. Unlike exocrine glands, which secrete their products through ducts that carry them to a specific location, endocrine glands release their hormones into the bloodstream to be distributed throughout the body. Some examples of endocrine glands include the pituitary gland, thyroid gland, adrenal gland, and pancreas.

Which of the following pairs of processes are incompatible, and therefore should not take place in the same place at the same time within cells? (select two answers) fatty acid oxidation; oxidative phosphorylation amino acid synthesis; protein degradation fatty acid synthesis; glycogen synthesis protein synthesis; protein degradation glycolysis, gluconeogenesis
The pair of processes that are incompatible and should not take place in the same place at the same time within cells are fatty acid oxidation and fatty acid synthesis.
Fatty acid oxidation involves the degradation of fatty acids to generate energy, while fatty acid synthesis involves the synthesis of fatty acids for storage. These two processes cannot occur simultaneously as they have opposing goals. The other pair of incompatible processes is glycolysis and gluconeogenesis, which involve the breakdown and synthesis of glucose, respectively.
These two processes cannot occur simultaneously as they also have opposing goals.
