The formula for cellular respiration is as follows: glucose oxygen carbon dioxide + water. In a class demonstration, Mrs. Nakaguchi takes a sugar packet and pours it on your desk. She then points a fan at the tiny mound of glucose supplying it with plenty of oxygen. "There we go, we are combining sugar with oxygen!" exclaims the teacher. The class eagerly waits...for nothing. You had the reactants necessary for cellular respiration, so why did nothing happen?
Answer:
In order for cellular respiration to take place, the reactants of glucose and oxygen must be combined in the presence of enzymes and energy. Without these components, the reaction cannot take place. Mrs. Nakaguchi had provided the reactants, but not the necessary components for the reaction to occur.

Answer:
Cellular respiration is a biological process that occurs in living cells, it needs enzymes and specific organelles to occur.
Explanation:
Cellular respiration is a complex biological process that converts the energy stored in glucose into a form that cells can use, called adenosine triphosphate (ATP). It is a multi-step process that occurs in several organelles in the cell, including the mitochondria. The process is catalyzed by enzymes, which are protein molecules that speed up chemical reactions. Without these enzymes and organelles, the glucose and oxygen molecules on the desk would not be able to react and produce carbon dioxide and water, which is the final product of cellular respiration. Even though the reactants were present, the necessary biological machinery for the process to occur was not.
Which one of the following systems responds fastest to environmental stimuli? a. nervous b. lymphatic c. immune d. muscular
Nervous systems responds fastest to environmental stimuli. The connections between an organism's neurons, which can result in neural pathways, neural circuits, and larger networks, influence how that organism sees the world and behaves.
The term "nervous system" refers to a particular class of cell known as the neuron. Neurons have a special structure that allows them to communicate with neighboring cells precisely and swiftly. These messages are transmitted by the cells through the axons as electrochemical impulses, which can either directly link with neighboring cells through electrical synapses or cause the release of neurotransmitters at chemical synapses. When an afflicted cell gets a synaptic signal from a neuron, it may be activated, inhibited, or vulnerable to different sorts of modulation.

how does bacterial transformation work? what do bacteria use it for? what do genetic engineers use it for?
Bacterial transformation is a process by which bacteria take up and incorporate foreign genetic material from their environment into their own DNA.
This process occurs naturally and is used by bacteria as a mechanism for acquiring new genetic information and adapting to changes in their environment. The transformed bacteria can then pass the new genetic information to their offspring, leading to the spread of the new traits within the population.
Genetic engineers use bacterial transformation as a tool for manipulating the genetic material of bacteria for various purposes. By introducing specific genes into bacteria, they can create bacteria that produce useful products, such as hormones or enzymes, or bacteria that are resistant to antibiotics.
Genetic engineering can also be used to study the function of specific genes by introducing them into bacteria and observing the effects.

A vesicle is a small sac or pouch that contains digestive chemicals. It is a type of organelle found in cells, and it is responsible for storing and releasing substances that are necessary for the cell to function properly.
Vesicles are found in both plant and animal cells, and they are typically filled with enzymes, hormones, and other molecules that are necessary for the cell to carry out its metabolic processes. In the digestive system, vesicles are responsible for releasing digestive enzymes that break down food into smaller molecules that can be absorbed by the body. They also help to transport molecules from one part of the digestive system to another.
Additionally, vesicles can be found in other areas of the body, such as the brain, where they are in charge of releasing neurotransmitters that assist in controlling bodily processes.
Vesicles are essential for the proper functioning of the body, and without them, many of the body’s processes would not be able to take place.

maximize the ability of diffusion and motor proteins to transport nutrients and waste products
The ability of diffusion as well as motor proteins to transfer nutrients and waste materials is maximised in small cells. The ability of a cell to send commands for cellular operations is influenced by cell size. Diffusion increases as surface area increases.
By enabling the transport of oxygen & food to cells within thick constructions to overcome diffusion limits, adequate vascularization is crucial for long-term survival and is a necessary component for fulfilling the promise of developing full-scale tissues and organs [205]. The rates of protein production, the folding speeds of its slowest proteins, as well as big cells—the rates of protein diffusion all serve as growth constraints on cells. The cell cycle in eukaryotes comprises four phases: G1, S, G2, & M. DNA replication takes place during the S and synthesis phase, and the cell divides during the M or mitotic phase. The other two phases, G1 and G2, sometimes known as the "gap phases," are equally significant but less striking.

involved in the mechanical and chemical breakdown of food is ___
The process involved in the mechanical and chemical breakdown of food is digestion. Digestion is the process by which food is broken down into its component parts, such as proteins, carbohydrates, lipids, and other nutrients.
Mechanical digestion involves the physical breakdown of food by the teeth, tongue, and stomach. Chemical digestion is the breakdown of food into its component molecules by enzymes produced in the stomach and small intestine. These enzymes act on the food molecules to break them down into smaller molecules that can be absorbed and used by the body.
The digestive system also produces other enzymes, such as bile, which helps break down dietary fats. The breakdown of food molecules into their component parts is the first step in the absorption of nutrients and the eventual production of energy.

One example is that scientists used to think that the primary role of metabolism was to produce energy in the form of ATP (adenosine triphosphate) and that it was a linear process with simple inputs and outputs.

what is inheritance of lactose?
The type of lactose intolerance that occurs in infants (congenital lactase deficiency) is inherited in an autosomal recessive pattern , which means both copies of the LCT gene in each cell have mutations.It's caused by an inherited genetic fault that means affected babies produce very little or no lactase. The genetic mutation responsible for congenital lactase deficiency is passed on in an autosomal recessive inheritance pattern. This means both parents must have a copy of the faulty gene to pass on the condition.Using both pedigree analysis and genetic analysis, scientists have discovered that the lactose-tolerance trait (lactase persistence) is autosomal dominant; individuals need to inherit only one copy of the lactose-tolerance allele to continue producing lactase as adults.To learn more about inheritance refers to:

Starch can be converted into glucose and used as an energy source for the plant when needed.
Glycogen, on the other hand, serves as a storage form of energy in animals. It is stored primarily in the liver and muscles and can be rapidly broken down into glucose as needed by the body for energy.
