The synthesis part of the term photosynthesis relates to the production of organic compounds.
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy that can be used to fuel their growth and metabolism. This process occurs in specialized structures within the cells called chloroplasts, which contain the pigment chlorophyll that absorbs light energy.
During photosynthesis, carbon dioxide from the atmosphere and water from the soil are converted into glucose, a simple sugar, and oxygen. This process involves a series of complex chemical reactions that are driven by the energy from light. The glucose produced by photosynthesis can be used immediately by the plant for energy, or it can be stored in the form of starch for later use.

what body system moves and supplies nutrients around the body
The circulatory system is responsible for moving and supplying nutrients around the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood.
The heart is a muscular organ that pumps blood through the blood vessels to deliver oxygen, nutrients, hormones, and other substances to the cells and tissues of the body. The blood vessels provide a network of tubes for the blood to flow through, and the capillaries are the smallest blood vessels that allow for the exchange of nutrients, oxygen, and waste products between the blood and the cells. The blood contains red blood cells, which carry oxygen, and white blood cells, which are involved in the immune system and help fight infections. Additionally, the circulatory system is responsible for removing waste products, such as carbon dioxide and other metabolic waste, from the cells and transporting them to the lungs and kidneys for elimination from the body.

The classic study by Harlow and Harlow (1958) demonstrated that when baby monkeys were deprived of physical contact with their mothers, they experienced a variety of developmental issues, such as increased fearfulness and decreased ability to form meaningful relationships.
The "wire mother/cloth mother" experiment was conducted by Harlow and Harlow in which they designed two artificial mothers for the baby monkeys. One of the mother's was made of wire, and the other one was made of soft cloth. They studied the behavior of monkeys with different mothers.
The experiment's outcome showed that the baby monkeys were strongly inclined towards the cloth mother and spent more time with the cloth mother rather than with the wire mother. This experiment reveals that the physical contact and attachment of the mother have a significant impact on the emotional and social development of the child.

Cyanide and carbon monoxide block the protein that donates the electrons to oxygen, thus forming water. Cyanide and carbon monoxide block ATP synthesis by:
a. inhibiting ATP synthase
b. preventing the formation of H+ ion concentration gradient
c. allowing H+ ions across the mitochondrial membrane without passing through the ATP synthase.
d. blocking oxygen diffusion into cells
e. blocking the pumping of H+ ions to the inside of the mitochondria
Cyanide and carbon monoxide block ATP synthesis by inhibiting ATP synthase. Cyanide and carbon monoxide are toxic substances. Thus, the correct option is A.
What is ATP synthesis?ATP synthesis is the process of producing ATP using energy from different sources such as glucose or lipids. The process occurs in the mitochondria of the cell. Cyanide and carbon monoxide are toxic substances that can inhibit ATP synthesis in the cell. Inhibiting ATP synthase is the way that cyanide and carbon monoxide block ATP synthesis. ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate. It is also responsible for creating a proton gradient across the inner mitochondrial membrane.
When this gradient is established, protons are pumped into the intermembrane space. This results in the formation of a proton-motive force that drives the phosphorylation of ADP to ATP. The blockage of ATP synthesis occurs as a result of the disruption of the proton gradient. Cyanide and carbon monoxide bind to cytochrome oxidase, an enzyme that is responsible for the transfer of electrons to oxygen during the electron transport chain. This causes the electrons to be trapped in the mitochondrial respiratory chain, which leads to a reduction in the proton gradient. Thus, ATP synthesis is inhibited.
Therefore, the correct option is A.

Explain how resting potential is maintained along an axon, the events that lead to an action potential, and the events of an action potential itself
The depolarizing current causes a burst of electrical activity called an action potential. This indicates that due to an action (stimulus), the resting potential becomes 0 mV.
The sodium/potassium pump uses ATP to transport 3 sodium ions out of the cell and 2 potassium ions into the cell, thus maintaining the resting membrane potential at the axon. This keeps the apparent negative charge of the neuron in place. The sodium-potassium pump sequentially removes three sodium ions from the cell for every two potassium ions introduced.
As such, it retains the significant gradient of potassium ions across the membrane that underlies the resting membrane potential.

1. Replicated DNA code will be: TAA CGTGAT; 2. mRNA codons are therefore: UAA CGU GAU ; 3. tRNA anticodons are: AUU CGC CUA; 4. Amino acid sequence is: Stop - Arg - Asp
What is codon?Sequence of three consecutive nucleotides in DNA or RNA molecule that codes for specific amino acid is called as codon.
Assuming the original DNA code is the template strand, the replicated DNA code will be:
TAA CGTGAT
To determine the mRNA codons, we need to transcribe DNA code into mRNA by replacing T with U: UAA CGUGAU
mRNA codons are therefore: UAA CGU GAU
The anticodon for UAA is AUU, which pairs with the codon UAA via complementary base pairing. The anticodon for CGU is GCA, which pairs with the codon CGU via complementary base pairing. The anticodon for GAU is CUA, which pairs with the codon GAU via complementary base pairing.
Therefore, tRNA anticodons are: AUU CGC CUA
To determine the amino acid sequence, we need to use genetic code to translate the mRNA codons into their corresponding amino acids.
UAA = Stop codon
CGU = Arginine (Arg)
GAU = Aspartic acid (Asp)
Therefore, amino acid sequence is: Stop - Arg - Asp

When an enzyme binds a non-competitive inhibitor, the vmax will decrease but the kd will not change.
An enzyme is a protein that acts as a biological catalyst by increasing the rate of chemical reactions in living organisms. The substrate is the molecule that an enzyme catalyzes, while the active site is the region of the enzyme where the substrate binds.
An enzyme inhibitor is a chemical or molecule that inhibits the action of an enzyme. Non-competitive inhibitors can bind to the enzyme either at the active site or at an allosteric site. The activity of the enzyme is decreased by non-competitive inhibitors that bind to allosteric sites.
As a result, the Vmax (maximum velocity of the reaction) decreases, but the Kd (dissociation constant) does not change. This implies that the affinity of the enzyme for the substrate does not alter.
The Michaelis-Menten equation can be used to study the effect of enzyme inhibitors on enzyme-catalyzed reactions.
