11. Initially transcribed as a proteolytic processing and transport before it enters the thylakoid lumen. 12. The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. 13. The reaction center is in the thylakoid membrane. 14. Plants depend critically on photosynthesis by chloroplast thylakoid membranes which are exposed cold environmental temperatures. 15. According to these studies, the thylakoid proteome consists of at least 335 different proteins. 16. Embedded in the thylakoid membrane are integral and peripheral membrane protein complexes of the photosynthetic system. 17. Attached to the thylakoid membrane, phycobilisomes act as light-harvesting antennae for the photosystems. 18. Practically all plastoglobuli form on or near the highly curved edges of the thylakoid disks or sheets. 19. Embedded in the thylakoid membranes are important protein complexes which carry out the light reactions of photosynthesis. 20. The number of thylakoids and the total thylakoid area of a chloroplast is influenced by light exposure.
