Nat 5 Cells

Respiration and photosynthesis

The three limiting factors of photosynthesis are temperature/light intensity/ carbon dioxide concentration
what happens in photolysis splitting water using light into hydrogen and oxygen
what is the by product in photosynthesis oxygen
what 2 products from the light dependent stage are needed for stage 2 ATP and H
What two products are made in the light dependent reaction ATP and H
what are the two stages of photosynthesis called light dependent and carbon fixation
describe how to measure the rate of photosynthesis count Oxygen bubbles PER minute
what are the 3 fates of carbohydrate in plants glucose for respiration, starch stored in leaves for energy and cellulose for structure in the cell wall
what happens in carbon fixation carbon dioxide combines with hydrogen in presence of ATP and enzymes to make glucose
What molecule absorbs light energy from the sun chlorophyll (not chloroplasts)
describe the 3 step energy conversion from the sun to making glucose in photosynthesis Light energy is trapped by chlorophyll in the chloroplasts Light energy is converted into chemical energy in the form of ATP. Chemical energy of ATP is used to make another form of chemical energy via glucose
what type of energy does ATP have chemical energy
what type of energy does glucose have chemical energy
what happens during glycolysis glucose is converted into pyruvate producing 2ATP
Describe the fermentation pathway in muscle cells glucose is converted into pyruvate which is converted into lactate/lactic acid
Describe the aerobic pathway in a cell glucose is converted into pyruvate without oxygen. Pyruvate is converted into water and carbon dioxide and 38ATP in presence of oxygen
what are the two products of aerobic respiration apart from ATP carbon dioxide and water
what are the two products of fermentation in yeast cells alcohol/ethanol and carbon dioxide (and 2 ATP)
what product (s) are produced during fermentation in animal cells lactat/lactate acid and 2ATP
Is fermentation in animals or plants/yeast reversible animals - reversible plants/yeast - permanent
what happens to yeast or plants during fermentation alcohol builds up and kills yeast/plant cell.
what stage of photosynthesis is temperature dependent stage 2 as Carbon fixation requires enzymes but stage 1 does not (and enzymes denature at high temperatures)
What two molecules make ATP ADP and Pi
Name the only process in the body that makes ATP respiration (aerobic or fermentation)
How much ATP is produced during fermentation 2 ATP
How much ATP is produced during aerobic respiration 38 ATP
Name a process that requires ATP active transport, muscle cell contraction, cell division, protein synthesis and transmission of nerve impulses
Location of glycolysis in a cell cytoplasm
location of aerobic respiration in a cell mitochondria
Location of fermentation in a cell cytoplasm
Does making or breaking ATP release energy making ATP (store of chemical energy)
What piece of equipment measures respiration respirometer
Describe a control experiment set up for a respirometer exact same set up but without animal that is respiring/dead animal
what does a control experiment prove that the animal is causing the respiration
What is measured via measuring the dye moving up the tube in the respirometer oxygen uptake per minute
name a gas that diffuses into a cell during aerobic respiration oxygen
name a gas that diffuses into a cell during photosynthesis carbon dioxide
name the two products that would diffuse out of a cell during aerobic respiration carbon dioxide and water
name the two products that would diffuse out of a cell during photosynthesis oxygen and glucose
