anaerobic respiration

Where does anaerobic respiration occur?

The cytoplasm

In anaerobic respiration in animals what is pyruvate converted to?

lactate

In anaerobic respiration in plants what is pyruvate converted to?

ethanol and carbon dioxide

What does pyruvate gain to form lactate?

hydrogen from reduced NAD

What does pyruvate gain to form ethanol?

hydrogen from reduced NAD

What are the two steps in anaerobic respiration?

1. Glycolysis

2. Lactate of ethanol formation

What are respiratory substrates?

molecules which can be broken down to provide energy for respiration

Which respiratory substrates provide the most to least energy?

1. lipids

2. proteins

3. carbohydrates

What causes more energy to be released from the respiratory substrate?

more hydrogens being released

What’s the respiratory quotient equation?

RQ = CO2 produced/ O2 consumed

What is the RQ value of carbohydrates?

1

What’s the RQ value of proteins?

0.9

What’s the RQ value of lipids?

0.7

why does the RQ only apply to aerobic respiration?

Anaerobic respiration doesn’t require oxygen

What’s a respirometer used for?

measuring the rate of oxygen consumption in respiration
