What is the mode of action of enzymes described by?

Cell membrane formation, organelle synthesis, and cellular respiration

Carbohydrate breakdown, fat synthesis, and protein digestion

Nucleic acid replication, DNA transcription, and RNA translation

Candidates should be able to: (a) state the main roles of carbohydrates, fats and proteins in living organisms: • carbohydrates as an immediate source of energy • fats for insulation and long-term storage of energy • proteins for growth and repair of cells (b) describe and carry out tests for: • starch (using iodine in potassium iodide solution) • reducing sugars (using Benedict’s solution) • protein (using biuret solution) • fats (using ethanol) (c) state that large molecules are synthesised from smaller basic units: • cellulose, glycogen and starch from glucose • polypeptides and proteins from amino acids • lipids such as fats from glycerol and fatty acids (d) explain the mode of action of enzymes in terms of an active site, enzyme-substrate complex and enzyme specificity using the ‘lock and key’ hypothesis (e) investigate and explain the effects of temperature and pH on the rate of enzyme catalysed reactions

7.03 Patients with Infectious Disease The center adheres to infection control policies to ensure the safety of patients, physicians, and staff members. Patients who are currently being treated for an infectious disease or condition that is transmitted via the contact route may not be treated at the center. Patients with disease spread via droplet (e.g. influenza) or airborne (e.g. tuberculosis, measles) routes will reschedule their procedures in consultation with their physicians. The infection control nurse, in consultation with the infection control consultant, will determine whether the patient requires isolation or other additional precautions. If a patient with current Clostridium difficile-associated diarrhea is treated at the center, all rooms where the patient was housed, even briefly, should be cleaned by housekeeping under supervision of the staff at the center. Physicians must document relevant information in their pre-admission documentation. Standard Precautions will be followed in the care of all patients. Cigarroa Interventional Institute establishes policies to ensure compliance with infection control policies for the care of patients with drug-resistant organisms. The physician will screen patients through the medical history review prior to scheduling a patient at the center. During the pre-operative (pre-op) phone call or interview, a pre-op screening of the patient will be conducted. Strict isolation policies are required to treat patients with active MRSA, VRSA, or tuberculosis. Since this facility has no provisions for strict isolation, those patients with active infections will be referred elsewhere for treatment. Patients who are undergoing or completed a course of antibiotic therapy, are colonized and/or are not actively infected may be treated at the center. Patients with active infections requiring transmission-based precautions are not appropriate candidates for this facility and will be referred to another facility or rescheduled. Procedures cannot be scheduled for patients currently undergoing an infection with transmission based precautions. The patient must finish the course, and they will be rescheduled. Definitions and Standards: The following definitions and standards are provided for informational purposes only: Airborne Transmission and Precautions: This mode of transmission occurs by the spreading of either airborne droplet nuclei (small particle residue of 5 microns or smaller), of evaporated droplets which contain microorganisms that remain suspended in the air for long periods of time) or dust particles containing microorganisms. Patients must be isolated in private rooms with special air handling and ventilation, and the door must remain closed. Patient transport should be restricted to essential transport only. Respiratory precautions must be taken when in the presence of patients with active tuberculosis, including respiratory masks. Droplet Transmission and Precautions: Droplets are transmitted from the host source by coughing, sneezing, talking, or during procedures such as suctioning or bronchoscopy. Patients must be isolated, and a distance of 3 feet maintained between the infected patient and others. Caregivers within 3 feet of the patient should wear a mask. Patient transport should be minimized. Contact Transmission and Precautions: Direct contact transmission involves direct body surface to body surface contact with physical transfer of microorganisms between a susceptible host and an infected person. Indirect contact transmission involves contact with an intermediate object (usually inanimate) and a susceptible host. Patients should be isolated as much as possible. Gloves and hand washing are essential for all contact with the patient and contact with objects, which come in contact with the patient. Gloves should be changed after each contact. Reportable Condition If the patient is determined to have a reportable condition at any time during pre-admission, the Director of Operations/Nurse Manager will be notified. The procedural physician will be contacted and the case will be canceled. The Department of Health will also be notified the same day following state regulations regarding Reportable Communicable Diseases. To report a disease or condition, contact: The City of Laredo Epidemiology 24/7 Reporting Line: (956) 763-2915, if unable to report locally, call The Texas Departmrent of Health Services epidemiology program: 24/7Number for Immediately Reportable – 1-800-705-8868
