Proteins and Enzymes AQA Biology Exam Questions

Digestive Enzymes and Locations
Ever wondered where your body produces the enzymes that break down your food? This question tests your knowledge of enzyme production in different digestive organs.
Amylase is produced by the pancreas and salivary glands - it's the enzyme that starts breaking down starch in your mouth and continues the job in your small intestine. Maltase, however, is produced by the small intestine itself, specifically in the brush border of intestinal cells.
The key concept here is enzyme specificity - maltase only catalyses the hydrolysis of maltose because enzymes have a specific active site shape. Think of it like a lock and key - maltase's active site perfectly complements maltose's shape, but won't fit other substrates.
Quick Tip: Remember that enzyme specificity comes from the unique 3D shape of the active site, which is determined by the enzyme's tertiary structure.
Industrial Enzyme Applications
Why would you attach lactase to beads instead of just mixing it directly into milk? This is all about industrial efficiency and cost-effectiveness.
Immobilised enzymes (attached to beads) offer three major advantages. First, you can easily separate and reuse the enzyme - no wastage! Second, the enzyme remains stable and doesn't get contaminated with the product. Third, you get continuous production as milk flows over the beads.
Here's something interesting about taste: lactose-free milk tastes sweeter than regular milk because lactase breaks down lactose into glucose and galactose. Both of these monosaccharides taste much sweeter than the original disaccharide lactose.
Remember: Immobilised enzymes are crucial in biotechnology because they're reusable, easily separated, and provide continuous production.
Bacterial Toxins and Stomach Ulcers
Helicobacter pylori isn't just any bacteria - it's the sneaky culprit behind most stomach ulcers. This experiment cleverly separates bacterial cells from their toxic products to see what actually causes damage.
Centrifugation works by spinning samples at high speed - heavier bacterial cells get forced to the bottom, leaving a clear, cell-free liquid containing only the substances the bacteria released. It's like using a super-powered spin cycle to separate different components.
The bacteria produce an acid-neutralising enzyme for survival - your stomach is incredibly acidic , so this enzyme creates a more comfortable environment for H. pylori to live and multiply. Pretty clever for a microscopic organism!
Key Insight: Lysosomes digest worn-out organelles and break down harmful substances - measuring their activity indicates cell damage levels.
Experimental Analysis and Toxin Effects
The data reveals something fascinating about bacterial pathogenesis. Strain A causes the most cell damage, while strain B (enzyme only) causes almost none.
This suggests the toxin is the main damage-causing agent, not the acid-neutralising enzyme. The enzyme might actually help the toxin work more effectively by creating better conditions for bacterial survival.
When scientists treated strain A's liquid with protein-digesting enzymes, all cell damage stopped. This proves the toxin must be a protein - once it's broken down, it can't harm cells anymore. This finding could be crucial for developing treatments.
Exam Tip: Always look at error bars in graphs - they show data reliability and help you make valid comparisons between results.
Homeostasis and Blood pH
Your blood pH must stay around 7.4 - even tiny changes can be deadly. This isn't just biological pickiness; it's absolutely essential for survival.
Enzymes are incredibly pH-sensitive because changes in pH alter their shape and destroy their active sites. If blood pH shifts, crucial enzymes stop working properly, disrupting vital metabolic processes throughout your body.
Think about it - every single chemical reaction in your body depends on enzymes. When pH changes disrupt enzyme function, you get a cascade of problems affecting everything from oxygen transport to cellular respiration.
Critical Point: Maintaining constant blood pH is vital because enzyme function depends on optimal pH conditions.
Cyanide Poisoning and Cellular Respiration
Cyanide is terrifyingly effective because it targets cytochrome oxidase, a crucial enzyme in the electron transport chain. Without this enzyme, electrons can't reach oxygen, and ATP production grinds to a halt.
The cyanide acts as a competitive inhibitor - it binds to the enzyme's active site, blocking the normal substrate and preventing the enzyme from functioning. This is why the antidote works by binding to cyanide molecules, effectively removing them from circulation.
Different organs show varying sensitivity to cyanide - notice how kidney tissues generally use more oxygen than liver tissues, and rat organs are more active than sheep or ox organs. This reflects the different metabolic demands of various tissues.
Life-Saver Fact: Antidotes work by binding to the poison, making it unavailable to interfere with normal biological processes.
Experimental Design and Data Analysis
This experiment demonstrates brilliant scientific methodology - using multiple animal organs and different cyanide concentrations provides robust, comparable data.
The grouping system allows for meaningful comparisons: you can compare different organs from the same animal, the same organ from different animals, or the effects of different cyanide concentrations. Group 1 (sheep liver vs kidney) shows kidneys are much more sensitive to cyanide than livers.
For the percentage calculation: rat liver drops from 10.0 to 1.9 oxygen units, giving a percentage difference of 81%. This massive drop demonstrates just how effectively cyanide shuts down cellular respiration.
Method Tip: Good experimental design always includes multiple comparisons and controls to ensure reliable, interpretable results.
Temperature Effects on Enzyme Activity
This classic enzyme experiment shows the temperature-activity relationship that's fundamental to biochemistry. The technician would need to control pH, substrate concentration, and enzyme concentration for valid results.
At 25°C, calculate the rate using the gradient of the initial straight-line portion of the curve. This gives you the initial rate of reaction before substrate depletion affects the results.
The 37°C curve shows faster initial reaction rate (steeper gradient) because higher temperature increases molecular motion and enzyme-substrate collisions. However, both curves level off as substrate gets used up - you can't make product faster than substrate availability allows.
Graph Skills: Always use the steepest part of the curve to calculate enzyme reaction rates - this represents optimal conditions before limiting factors take effect.
Rate Calculations and Curve Analysis
The rate calculation requires measuring the gradient of the steepest part of each curve - this represents maximum enzyme activity before substrate becomes limiting.
The differences between curves reflect the effect of temperature on enzyme kinetic energy. At 37°C, molecules move faster, leading to more frequent enzyme-substrate collisions and higher reaction rates initially.
Both curves eventually plateau because substrate concentration becomes the limiting factor. No matter how active your enzyme is, it can't work faster than substrate availability allows - this is a key principle in enzyme kinetics.
Calculation Reminder: Rate = change in concentration ÷ time, using the steepest linear portion of your curve for most accurate results.
