Question
Chapter 20, Problem 21P
Interpretation Introduction
Interpretation:
A detailed description about C3 and C4 mechanisms would be necessary to make a comparison between them.
Concept introduction:
Photosynthesis is the process by which plants store energy from sunlight as chemical energy.The process happens in the chloroplast of a plant cell.There are two mechanisms by which the plants fixes CO2, that is, C3 and C4 cycle. Each green plant uses one of these two mechanisms.

mammalian cell homogenate? Assume that glycolysis, the
citric acid cycle, and oxidative phosphorylation are fully
active.

phosphate
true or false
1. Phosphoenolpyruvate carboxykinase is the enzyme involved in the carbon dioxide fixation in the mesophyll cells of C4 plants
2. The C4 pathway utilizes less ATP than C3 pathway thus enabling C4 plants to adapt to tropical temperatures.
3. Photorespiration occurs when [O2]/[CO2] is high.
4. The carboxylase activity of RuBisCO catalyzes the fixation of carbon dioxide.
5. In cyclic photophosphorylation, only ATP is produced.
6. Chlorophyll has iron as the metal center of the porphyrin ring.
Help is appreciated. Think of an unusual eukaryotic species in which its ATP synthase has 12 subunits for its c ring. How many ATP molecules can be produced per pair of electrons that traverse the respiratory chian starting at Complex I?
A. 2 ATP/2e-
B. 1 ATP/2e-
C. 0.5 ATP/2e-

The hydrogen added on the end of the formula is an indication that NAD has been reduced. As you read in the textb0ook section on oxidative phosphorylation, a series of redox reactions oxidize NADH back to NAD. All redox reactions are paired oxidation and reduction reactions, so what was reduced? Ultimately O2 is reduced to H2O (note the addition of hydrogen due to reduction). Oxygen is said to be the final electron acceptor, as no further redox reactions take place. In lab we will again look at differences among bacteria in their metabolism as a way to distinguish different species. First we will look at anaerobic respiration. When oxygen levels are low, some microbe can use a different compound than oxygen as their final electron acceptor. Sulfate SO,, carbonate CO3²", and nitrate NO; are all common alternatives, rich in oxygen, which can accept those electrons.…arrow_forward1a.

Tumor without relying on oxidative phosphorylation to generate energy, a pro- cess known as the "Warburg effect". While less efficient at generating ATP, it has been proposed that the Warburg effect promotes prolifera- tion by generating an abundance of glycolytic intermediates that serve as precursors for other anabolic processes to generate biomass. One consequence of the Warburg effect is that cancer cells that are not bathed in a constant source of fresh glucose – such as cells in a solid tumor that are far from any capillaries (e.g., non-small cell (NSC) lung cancer) – often run out of glucose and activate gluconeogenesis. In this situation, the lactate generated by anerobic glycolysis is converted back to pyruvate to begin gluconeogenesis. or +/-02 Glucose Pyruvate 5% 85% Lactate CO2 (a) matic steps.
