Photosynthesis produces A T P and NADPH
What are thylakoid membrane?
The thylakoid membrane is site of photochemical and electron transport reactions of oxygenic photosynthesis.
Photosynthesis takes place in the two distinct stages.
In light reactions, energy from the sunlight drives the synthesis of ATP and NADPH, coupled to formation of O2 from H2O.
In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by light reactions drive glucose synthesis.

The thing unusual about the process is that Photosynthesis produces A T P and N A D P H.
What is photosynthesis?
Plants, algae, and some microbes convert sunlight into energy through a process called photosynthesis. The procedure chemically transforms water and carbon dioxide (CO2) into food (sugars) and oxygen. Chlorophyll, the pigment that gives plants their green color, is frequently a key component of the chemical reaction.
The two separate stages of photosynthesis occur.
Energy from sunlight powers the synthesis of ATP and NADPH in light processes, along with the oxidation of water to produce oxygen (O2).Because they don't require sunlight, the dark reactions are so-called because they utilise the ATP and NADPH generated by light reactions to power the synthesis of glucose.
Therefore the thing unusual about the process is that Photosynthesis produces A T P and N A D P H.

suppose you were to activate a skeletal muscle fiber that is at a very short length such that the thin filaments from opposite sides of the sarcomere ran into each other and the m-line? what would happen to skeletal muscle fiber force production at that length when an action potential was generated?
Skeletal muscle fiber force production at that length when an action potential was generated will the sarcomeres would generate very little force.
The fundamental unit of contractility for muscle fiber is the sarcomere. Actin and myosin, the active components involved in muscle contraction, make up each of the two primary protein filaments that make up a sarcomere.
In skeletal muscle, the sarcomere serves as the primary contractile unit of muscle fiber. The thick filaments known as myosin and the thin filaments known as actin make up the majority of each sarcomere's protein filaments (myofilaments).
Because the actin and myosin filaments that drive skeletal and cardiac muscles' contraction are arranged into repeating arrays called sarcomeres, which have a striated microscopic appearance, these muscles are referred to as striated muscles.

OC. an increased need for gerontologists and other professionals to care for the elderly OD. an increase in the relative frequency of deaths from cancer an increase in the total population of humans on the planet
Answer:
Explanation:
It is possible that some of the following options could be described as ecological consequences of passing the upper limit for human life expectancy:
A. a decrease in the birth rate: If the population has a higher proportion of older individuals, this could lead to a decrease in the birth rate, as fewer people are of childbearing age.
C. an increased need for gerontologists and other professionals to care for the elderly: As the population ages, there may be an increased need for medical professionals and caregivers to support the elderly.
D. an increase in the relative frequency of deaths from cancer: As people live longer, they may be more likely to develop age-related diseases such as cancer, which could lead to an increase in the relative frequency of deaths from these causes.
It is important to note that these potential consequences are not necessarily inevitable or certain to occur, and there may be other factors at play that could influence the outcomes described above.

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.

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 pH scale is a mathematical indicator of the total amount of all ions in a solution. A collection of standard solutions with pH values that have been agreed upon internationally can be used to trace the pH scale.
The primary pH standard values are determined by measuring the potential difference between a hydrogen electrode and a standard electrode, such as the silver chloride electrode, using a concentration cell with transference. You can use a glass electrode, a pH meter, or a color-changing indicator to determine the pH of aqueous solutions. Numerous disciplines, including chemistry, agronomy, medicine, water treatment, and many more, depend on pH measurements.
A water molecule is created when two hydrogen atoms form a covalent bond with an oxygen atom. Within a covalent bond, atoms share electrons. Water is distributed in an unequal manner. The oxygen atom attracts electrons more forcefully than hydrogen does. Charges are now distributed differently in the water.

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).
