Lecture #1

Question 1

How is “Marine Biochemistry and Physiology” different from “Regular Biochemistry and Physiology”?

Answer 1

• differing situations derived from being surrounded by water
• gases, salinity, light, pressure, temperature, waste excretions, pollutants, locomotion

Question 2

What is the importance of Basic Research? What are some examples of Marine Biochemistry applications?

Answer 2

• fascinating, reveals interesting adaptations to extreme environments, never know where it will lead
• to fix things, we need to know how they work
• improves understanding of effects of stressors
• biotechnology (biofuels, aquaculture, etc…)

Question 3

What is homeostasis?

Answer 3

the ability of an organism to maintain internal stability in spite of metabolic and environmental disturbances

Question 4

Why does homeostasis require energy?

Answer 4

• costs energy to decrease entropy

- system tends toward entropy, keeping it stable means fighting against that

Question 5

What are the two main pathways of ATP production?

Answer 5

aerobic and anaerobic
