Ribulose bisphosphate carboxylase How many times does the Calvin-Benson Cycle need to turn to make 1 hexose sugar? Update From the comments below, there seems to be some confusion about what exact indicator is used in this experiment.
The hydrogencarbonate changes colour from red to purple due to the change in acidity. One teacher starts with homeostasis but not nerves and then does excretion, Cellular control and the bulk of biotechnology. What occurs once O2 has left during the light-dependent reaction?
Triose phosphate 3C What does GP stand for? In the Autumn we split the course in half as we have two teachers. This is to try and split the content as easily as possible and build on how we previously taught the course.
ScienceGuy Occasional commenter My centre has had a big rethink as to how we will teach this course due to the removal of the January modules. A chain of proteins through which excited elctrons flow 49 of 80 What process occurs during the light-dependent 1st reaction? The pondweed photosynthesises decreasing the level of CO2 in the water.
As the carbon dioxide in the water has decreased, the acidity of the water decreases causing the indicator to change from red to purple. Cover tube 1 completely with aluminium foil to exclude light. What occurs at the start of the light-dependent reaction? Electron transport chain What is an electron transport chain?
This helps making the test valid because you will be able to stop the clock at the same specific shade of purple for each test tube of pondweed. What occurs once excited electrons have moved along the ETC during the light-dependent reaction? Place tube 2 directly next to a light source such as a lamp and then tube 3 directly 10cm away from the light source.
The main advantage on how we used to teach the content is that we can link nerves for communication and the role in muscles more closely and teach all the plant biology together We plan the practical assessmets to fit in with the content, doing the practicals as close to when they have been taught the conntent as possible.
Close each test tube with a rubber bung. This shows the higher the light intensity, the less time it takes for the indicator to go purple. Labelling the tubes to stop contamination. What occurs on the creation of a proton gradient across the membrane of the thylakoid during the light-dependent reaction?
Hydrogencarbonate indicator also known as biocarbonate indicator is used because it is a pH indicator that is sensitive enough to display a colour change when the levels of carbon dioxide changes.Related discussions on The Student Room.

This article will have all you need to know about the Biology IAA coursework on the investigation into the effect of light intensity on the rate of photosynthesis.
Yes, another boring IAA exam which makes it vital to have no slip ups in the method, validity, reliability, evaluation or conclusion. biology at Level 3 in the National Qualifications Framework (NQF).
The AS specification has been written to provide progression from GCSE Science and GCSE Additional Science, or from GCSE Biology; achievement at a minimum of grade C in these qualifications should be seen as the normal requisite for entry to AS Biology.
