[3] An increase in these two molecules led to the initiation of chlororespiration. [3] N-propyl gallate was also added to these water deficit plants. The effect resulted in increased chlorophyll fluorescence levels. [3] Quiles recorded a similar outcome in the same species of plants that went under intense light.
The only chloroplast structure that can be considered analogous to it is the internal thylakoid system. Even so, in terms of "in-out", the direction of chloroplast H + ion flow is in the opposite direction compared to oxidative phosphorylation in mitochondria.
Within the envelope membranes, in the region called the stroma, there is a system of interconnecting flattened membrane compartments, called the thylakoids.The thylakoid membrane is quite similar in lipid composition to the inner envelope membrane, containing 78% galactolipids, 15.5% phospholipids and 6.5% sulfolipids in spinach chloroplasts.

A diagram of a chloroplast. The TIC and TOC complexes are located on different sides of the chloroplast membrane.. The TIC and TOC complexes are translocons located in the chloroplast of a eukaryotic cell, that is, protein complexes that facilitate the transfer of proteins in and out through the chloroplast's membrane.
The chloroplast may be discoid, cup-shaped (e.g. Chlamydomonas), spiral or ribbon shaped. [example needed] Most chlorophytes have one or more storage bodies called pyrenoids (central proteinaceous body covered with a starch sheath) that are localised around the chloroplast. Some algae may also store food in the form of oil droplets.
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. [1] Within the stroma are grana (stacks of thylakoid), the sub-organelles where photosynthesis is started [2] before the chemical changes are completed in the stroma. [3] Photosynthesis occurs in two stages.

These data have been summarized in several plastid protein databases that are available online. [22] [23] According to these studies, the thylakoid proteome consists of at least 335 different proteins. Out of these, 89 are in the lumen, 116 are integral membrane proteins, 62 are peripheral proteins on the stroma side, and 68 peripheral proteins ...
