calculate the total number of oxygen, nadph, and atp molecules that are produced when 12 water molecules complete the light-dependent reactions
6 O2 molecules, 12 NADPH molecules, and 18 ATP molecules are produced when 12 water molecules complete the light-dependent reactions.
What are light-dependent reactions?
In the presence of sunshine, light-dependent processes take place in the thylakoid membrane of the chloroplasts. These processes transform the solar energy into chemical energy. The photosynthesis process is carried out by the photosystem, which receives energy from the sun through the chlorophyll in plants.
They need light to function, and their overall conversion of water molecules to oxygen produces ATP molecules from ADP and Pi and NADPH molecules from the reduction of NADP+. The Calvin cycle can employ the ATP and NADPH that are created on the stroma side of the thylakoid membrane.
The "normal" form of the light-dependent processes, known as non-cyclic photophosphorylation, involves the removal of electrons from water and their passage via PSII and PSI before arriving at NADPH. Light must be absorbed twice throughout this process, once in each photosystem, in order to produce ATP. In fact, it uses light energy (photo) to create ATP from ADP, hence the name "photophosphorylation" (phosphorylation).

chromatin remodeling by the swi/snf complex requires hydrolysis of atp. what purpose does this serve?
It serves two main functions when DNA is wrapped around histones to form chromatin structure: first, it causes condensation of the long (many meters) DNA strand so that it can fit into the nucleus appropriately. Second, it prevents DNA from being transcribed continuously.
To begin gene expression, chromatin must first be unwrapped, a
process known as chromatin remodeling. It follows that chromatin remodeling is an essential step for regulating key physiological functions and preserving cellular homeostasis. Additionally, gene expression is inherently dependent on chromatin remodeling. The process, which requires ATP for energy, is nearly totally marked by the release of the TATA binding protein (TBP) from the somatic chromatin. An ISWI-containing remodeling factor is an essential component in this substantial chromatin remodeling in vitro. By relocating, assembling, mobilizing, and rearranging nucleosomes, ATP-dependent chromatin remodeling complexes change the chromatin structure. Hence, The SWI/SNF chromatin remodeling complex performs crucial functions in DNA-based activities by facilitating chromatin access using the energy of ATP hydrolysis.

the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantages for the pathogen? group of answer choices pathogens have larger population sizes and shorter generation times than hosts, allowing for increased rates of adaptation. pathogens have lower mutation rates than hosts, resulting in more stable populations. hosts evolve more rapidly due to mutations induced by the pathogen. host population sizes increase in the presence of a pathogen, providing more potential hosts for infection.
Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.
Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill.
