directions: choose the best answer for each question

1. when oxygen is not available, what process do cells use to generate a small amount of atp?

a) aerobic cellular respiration
b) anaerobic cellular respiration
c) photosynthesis
d) dehydration synthesis

1. the pancreas releases glucagon in response to a change in blood sugar. what is the primary effect of glucagon?

a) it causes the liver to release stored glucose from glycogen
b) it makes cells take up more glucose from the blood
c) it increases cellular respiration in all cells throughout the body
d) it promotes the storage of glucose as fat

1. what is the primary purpose of cellular respiration?

a) to produce glucose
b) to release energy from food to produce atp
c) to break down water molecules
d) to create carbon dioxide for photosynthesis

1. which system is primarily responsible for coordinating the bodys response to internal and external changes to maintain homeostasis?

a) the digestive system
b) the nervous and endocrine systems
c) the respiratory system
d) the circulatory system

Explanation:

1. Aerobic cellular respiration requires oxygen. Photosynthesis is for plants to make glucose using light energy. Dehydration synthesis is a chemical - bonding process. Anaerobic cellular respiration occurs without oxygen to produce a small amount of ATP.
2. Glucagon is a hormone that raises blood sugar levels by making the liver release stored glucose from glycogen. Insulin makes cells take up more glucose. Glucagon doesn't directly increase cellular respiration in all cells or promote glucose storage as fat.
3. Cellular respiration is the process of breaking down food to release energy in the form of ATP. It doesn't produce glucose, break down water molecules mainly, or create carbon - dioxide for photosynthesis as its primary purpose.
4. The digestive system is for breaking down food. The respiratory system is for gas exchange. The circulatory system is for transporting substances. The nervous and endocrine systems work together to coordinate the body's response to internal and external changes to maintain homeostasis.

Answer:

1. b) Anaerobic cellular respiration
2. a) It causes the liver to release stored glucose from glycogen
3. b) To release energy from food to produce ATP
4. b) The nervous and endocrine systems
