- Hello, I do not understand these questions, can I get help with them, please? Below are 3 statements, explain if each is true/false and why (VERY brief statement) #1: A tropic hormone always increases the size of an endocrine gland. #2: Spontaneous action potentials in the heart are primarily triggered by flux of K+ into cells through If channels. #3: Increasing the frequency of action potentials in motor units generates more tension than increasing the number of motor units.In what ways do steroid hormones differ from peptide hormones? More than one aswer may be correct. Question 12 options: They bind to a receptor inside the cell They circulate bound to plasma proteins They are derived from cholesterol They are hydrophilic They passively diffuse out of the cellOne of the main endocrine glands in the human body is the pituitary gland. This gland produces a variety of hormones with different effects. Among these are a heterogeneous group of hormones called tropic hormones, which directly stimulate the secretion of other hormones from downstream endocrine glands. Which of the following are tropic hormones? Select all that apply. LH Prolactin Oxytocin ACTH TSH testosterone
