Answer:
Phospholipids and proteins
Explanation:
The cell membrane is primarily composed of a phospholipid bilayer. The phospholipid molecules are made of a hydrophilic phosphate head and a hydrophobic fatty acid tail. These form a bilayer arrangement and act as a semi-permeable membrane.
There are also many proteins embedded in the phospholipid bilayer. These proteins act as channels, shuttles, transporters, enzymes, and signalling molecules to control the access of materials that cannot cross the bilayer and to respond to the extracellular environment.

Answer:
The correct answer would be They comprise the Calvin cycle.
Calvin cycle refers to the set of chemical reactions taking place in the stroma of the chloroplast in which carbon is fixed into food (glucose). The whole process is divided into three stages namely: fixation, reduction, and regeneration (ribulose bisphosphate or RuBP).
It takes place in light-independent reaction of the the photosynthesis.
It does not require light energy to carry out the reactions however, it depends upon the products of light reaction (ATP and NADPH).
Fixation of one molecule of glucose requires 6 molecules of carbon dioxide, 9 ATP and 6 NADPH.
The fixation of carbon is catalyzed by an enzyme RuBisCO.
The first steps of catabolism generally take place in the cytosol.
Glycolysis and pentose phosphate pathway are metabolic process that occurs inside of the cytosol. Other catabolic processes such as the citric acid cycle, electron transport chain, and oxidative phosphorylation all take place in the mitochondrial membrane.
