Q

Transmission electron microscope’s

A

Have a higher magnification and resolution than light microscopes but they’re not portable expensive and it’s complicated process to prepare specimens for use

Q

Preparing specimen for the light microscopy

A
  1. If thick take thin slice to start with
  2. Take it clean slide and use a slide to Put one drop of water in the middle of it
  3. Used tweezers to put specimen on the slide
  4. Add a drop of stain if needed
  5. Place coverslip
  6. Carefully lower cover slip onto slide press it down gently so that no hair bubbles are trapped under it

Q

Translation

A

The mRNA molecule then moves out of the nucleus and into the cytoplasm amino acids that match the triplet code is on the mRNA or join together in the correct order this makes the protein.

Q

ATP

A

The energy transferred by respiration can’t be directly used by cells so it’s used to make a substance called ATP

ATP stores the energy needed for many cell processes

16
Q

What is respiration controlled by?

A

Enzymes (glucose is substrate)

17
Q

Aerobic respiration

A

Happens when there is plenty of oxygen available and it’s the most efficient way to transfer energy from glucose (lots of ATP produced)

18
Q

Equation for anaerobic respiration

A

Glucose > Lactic acid

19
Q

Equation for anaerobic respiration in plants

A

Glucose > Ethanol + Carbon dioxide

20
Q

Experiment to demonstrate CO2 production buy some beans

A
  1. Use hydrogen carbonate solution to a test tube
  2. Soak dried beans in water so they germinate
  3. Place beans onto platform made of gauze
  4. After about an hour hydrogen carbonate should be yellow due to CO2 production
21
Q

What do you carbohydrate molecules contain

A

Carbon, Hydrogen, Oxygen

22
Q

What atoms you amino acids contain

A

Carbon, nitrogen, hydrogen, and oxygen

23
Q

Where are proteins are broken down

A

Proteins are broken down by enzymes in the stomach and small intestine

24
Q

What are lipids made up of

A

Glycerol and three fatty acids

Not polymers because they don’t form a long chain of repeating units

25
Q

What do lipids contain

A

Carbon, hydrogen, and oxygen atoms

26
Q

What are lipids are broken down by

A

In the body lipids are broken down by enzymes in the small intestine

27
Q

Two stages of photosynthesis

A
  1. Energy transferred by light is used to split water into oxygen gas and hydrogen ions
  2. Carbon dioxide gas then combines with hydrogen ions to make glucose
28
Q

What affects rate of photosynthesis

A

Light intensity, carbon dioxide, Temperature
