Why do we need oxygen?

Select one:

a. It is the final electron acceptor in the electron transport chain

b. It is needed to change the blood's pH

c. It activates pepsinogen into pepsin

d. Bacteria require it to break down plant products in large intestine

e. It is needed for glycolysis to occur

Explain the ways in which aerobic respiration and fermentation processes are different. Name the three phases of aerobic respiration and give the starting materials and end products of each phase. Describe a difference in the glycolysis pathways of bacteria and eukaryotic microorganisms. Describe how a bacterium uses an electrochemical gradient to generate ATP.

What is the difference between positive and negative feedback?

What is the difference between an endergonic and exergonic reaction?

What's needed to go on to kreb cycle, what's need to go into electron transport chain?

What are the end products and amount for glycolysis, krebs cycle and electron transport chain?

(in detail- thanks)

Glycolysis (and its sister pathway gluconeogenesis) and the citric acid cycle are often referred to as the Central metabolic Pathways. Identify at least 3 other metabolic in aerobic organisms (animal and or plant) that interact with these two central pathways. Briefly describe the connections and conditions that govern the flow of energy and shared intermediates

Give the location, whether it is anaerobic or aerobic and the net production, (Per Glucose) of the listed compounds:

a. Glycolysis: ATP, NADH, Pyruvic Acid

b. Prep Step ( Intermediate Stage): ATP, CO2, NADH

c. Krebs Cycle: ATP, CO2, NADH,FADH2

d. Oxidative Phosphorylation: ATP

Which foods are sources of saturated fats and trans fatty acids and why should they be avoided?

Explain the regulation of the allosteric enzyme acetyl-CoA carboxylase by citrate and palmitoyl-CoA.
