Question
Chapter 8.4, Problem 2EQ
Summary Introduction
To determine: The use of 14C labelled CO2 in the experiment of the Calvin cycle.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that uses the energy from the light-dependent reactions. It then employs the energy (ATP and NADPH) to synthesize carbohydrates that can be further used by the plant.
Summary Introduction
To determine: The results of the examination of the samples taken from the Calvin cycle at different times.
Introduction: The Calvin cycle is a light-independent photosynthetic reaction that was discovered by Melvin Calvin, Andrew Benson and their colleagues. The cycle uses energy from the light-dependent reactions.
Summary Introduction
To determine: The method by which different samples were identified in the experiment.

Introduction
Cellular respiration (sometimes called aerobic respiration) occurs in all animal and
plant organisms (with a few exceptions). This is the process where food substances such
as glucose are metabolised (using oxygen) to produce carbon dioxide and energy. It
basically consists of three parts ie glycolysis, Krebs' cycle and oxidative phosphorylation
linked to electron transport and chemiosmosis. At the end of the process large amounts
of energy in the form of ATP are produced, for cell metabolism and growth.
Part 1. Experiments on cellular respiration.
Experiment 1
In an investigation of aerobic respiration was carried out using isolated mitochondria.
Were added to a prepared medium containing succinate and inorganic phosphate.
Note: The mitochondria were isolated from liver cells by the following method:
1.
The liver tissue was ground with sand in a pestle and mortar, containing a
phosphate buffer at pH 7.0, and 0.4 % sucrose solution, at 4°C.
2. The homogenate was spun…
With the advent of photosynthesis, the amount of oxygen in the atmosphere has varied
over the eons up to 35 % by volume, theoretically leading to larger plants and animals.
The current concentration is 21 % oxygen, 78 % nitrogen, and 1 % other gases such as
argon and carbon dioxide.
Assuming an atmosphere of 16 % oxygen, to the nearest whole number (no decimal)
what would be the ideal volume of water (in mL) initially placed in a 25 mL graduated
cylinder (assuming the graduation goes up to the lip of the container) for optimal
combustion (biggest explosion) if we collected pure hydrogen by displacement as in this
experiment? Make sure to account for the stoichiometry of the combustion, that all
gases involved are diatomic, and that equal moles of different ideal gases occupy equal
volumes at the same temperature.
