Metabolism is a broad term that includes all chemical reactions that occur within body cells. It includes breaking down substanc
es into simpler building blocks (the process of catabolism), synthesizing more complex cellular structures from simpler substances (anabolism), and using nutrients and oxygen to produce (via cellular respiration) ATP, the energy-rich molecules that power cellular activities. What is false about metabolism?
The statement that is false is <u>metabolism is regulated largely by the nervous system.</u>
Explanation:
The metabolism reactions are controlled by the enzymes specific for each metabolic reactions. After a signal is generated, specific enzymes that detect the signal starts up the metabolic reactions.
When there is a need to stop a certain metabolic reaction, then the mechanism of feedback inhibition is used which stops the enzyme from carrying out any further reactions. Hence, the statement that metabolism is regulated largely by the nervous system is false.
The correct answers are a. vaginal ring and c. oral contraceptives.
The vaginal ring is a soft, plastic ring that releases a continuous dose of the hormones oestrogen and progestogen into the bloodstream and prevents pregnancy. Oral contraceptives are also drugs for preventing pregnacy and also contain combinations of the hormones estrogen and progestin )or progestin alone=. Estrogen and progestin inhibit the release of the hormones luteinizing hormone (LH) and follicle stimulating hormone (FSH) which have a role in the ovulation.
