Glucose, often known as dextrose or simple sugars, is one of the carbohydrate (monosaccharides).
What happens if you eat too much carbohydrates?An excessive consumption of carbohydrates strains the body's metabolic processes. Over time, ingesting both sugar and starch raises blood sugar levels, which contributes to weight gain, poor metabolism, and an increased risk of heart disease.
What normal blood sugar level corresponds to age?Between 5.0 and 7.2 mmol/L for adults, or 90 to 130 mg/dL. The range is 5.0 to 7.2 mmol/L (90 to 130 mg/dL) for children ages 13 to 19. 90 to 180 mg/dL (5.0–10.0 mmol/L) is the recommended range for children aged 6 to 12. 5.5 to 10.0 mmol/L, or between 100 and 180 mg/dL, for children under the age of six.

The right answer is C. Almost all organisms engage in glycolysis, which does not necessitate membrane-bound organelles.
Short answer: What is glycolysis?The process by which carbohydrate is taken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the the cell's cytoplasm. Both and anaerobic creatures experience it.
Why is glycolysis important? What is it?One glucose is oxidatively broken down into two pyruvates as part of the glycolysis metabolic pathway, and some energy is captured as ATP and NADH. Since glucose serves as the body's primary energy source for tissues, glycolysis plays a crucial role in the cell.

the ans regulation of blood pressure is involuntary, yet biofeedback techniques enable individuals to reduce their pulse rate and blood pressure. explain how this occurs.
High blood pressure and pulse rate of the individual are reduced by the biofeedback method in which an individual's physiological parameters are visualized in instruments based on values in instrument blood pressure and pulse rate can be reduced by therapies.
Biofeedback is a technique in which individuals are trained to control their involuntary body function which is usually controlled by ANS (Autonomic Nervous System). This is possible because individuals who are in biofeedback therapy sessions are monitored by equipment that can sense physiological functions. This equipment converts physiological signals into auditory, and visual signals hence the patient and therapist can see or hear how the body is reacting to stimuli. Through techniques suggested by therapists, patients can control involuntary physiological functions of the body. Using biofeedback equipment physiological parameters like breathing rate, heart rhythm, finger temperature, and muscle activity of patients with high blood pressure will be collected. On basis of the physiological parameters, the result therapist will design a training program for the patient.

It activates CDK1 by cyclin A, causing the cells to enter the transition to the M phase.
What is cell cycle?
The cell cycle is made up of several steps in which the chromosomes and other cell components replicate themselves to make two copies. The material is then duplicated and given to each of the two daughter cells as the cell divides. Each daughter cell must have its own outer membrane for the cell cycle to be complete.
What is cyclin?
Cyclins are a family of proteins that do not themselves have any enzymatic activity but instead work by binding to CDKs to activate them.
By phosphorylating CDC6 and E2F1, the cyclin A/CDK2 complex ends the S phase, initiates the transition from the S phase to the G2 phase, and then activates CDK1 by cyclin A, causing the cells to enter the transition to the M phase.
