Yes that is a true statement
At a fundamental level, water provides electrons to replace those removed from chlorophyll in photosystem II. Also, water produces oxygen as well as reduces NADP to NADPH (required in the Calvin cycle) by liberating H+ ions
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Water also has another important role of being an electron feeder. In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll. This loss of electron must be fulfilled by electrons from some other reducing agent. Photosystem II involves the first few steps of the Z-scheme (the diagram of the electron transport chain in photosynthesis) and therefore a reducing agent that can donate electrons is required to oxidize chlorophyll, which is provided by water (acting as a source of electrons in green plants and cynobacteria). Hydrogen ions thus released create a chemical potential (chemiosmotic) across the membrane that finally results in synthesis of ATP. Photosystem II is the primary known enzyme that acts as catalyst in this oxidation of water.

Answer:
Autism spectrum disorder
Explanation:
According to DSM-V, autism spectrum disorder is a neurological and developmental disorder that has the following symptoms:
- Persistent deficits in social communication and social interaction across multiple contexts: social-emotional reciprocity, reduced sharing of interests, emotions or affect, failure to initiate or respond to social interactions.
- Persistent deficits in nonverbal communicative behaviors used for social interaction: poor verbal and nonverbal communication, abnormal eye contact or body language, poor use of gestures.
- Persistent deficits in developing, maintaining, and understand relationships.
- Restricted, repetitive patterns of behavior, interests, or activities: stereotyped or repetitive motor movements or phrases, inflexible adherence to routines, fixated interests,
Thus, this disorder involves a wide range of problematic behaviors including deficits in language and perceptual and motor development; defective reality testing; and impairments in social communication.
