B1.3 Flashcards
What does carbohydrase break carbs into?
Sugar molecules
What does amylase break down starch into?
Glucose
What does lipase break lipids (e.g fats,oil) into
fatty acids and glycerol
What is metabolic rate?
The rate at which chemical reactions in cells transfer energy from chemical stores in food
What is the equation for aerobic respiration?
Glucose + oxygen -> carbon dioxide + water
What does respiration also produce not shown in equations
ATP (energy)(adenosine triphosphate)
What are the uses of ATP
Protein synthesis, warmth, movement
Where does aerobic respiration take place?
Mitochondria
What is the equation of anaerobic respiration?
Glucose -> lactic acid
What is the equation for fermentation?
Glucose -> ethanol + carbon dioxide
What are the drawbacks of anaerobic respiration
Way less energy as the glucose isnt fully broken, poisonous lactic acid can cause e.g cramps, oxygen debt to recompensate
Why would we need to respire anaerobically
During short bursts of energy usage (e.g 100m race)
What monomer does protein break down into?
Amino Acids
Why does bread eventually become sweet if you chew it for a long time?
The starch breaks down into glucose (sugars) after reacting with amylase
What are the roles of carbohydrates
Provide the body with energy
