What is metabolic activity in a cell?
Metabolic activity is the constant flow of molecules through metabolic pathways that maintains an organism's life.
What is an organisms chemical activity called?
metabolic activity
Which of the following is not used to determine metabolic activity?
Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
Where does most of the metabolic activity in a cell occur?
Most of the metabolic activity in a cell occurs in the mitochondria, where energy production through cellular respiration takes place. Additionally, the cytoplasm is also important for various metabolic processes such as glycolysis and protein synthesis.
Is aerobic respiration a metabolic activity?
Yes, aerobic respiration is a metabolic activity that involves breaking down glucose to produce ATP in the presence of oxygen. It is a crucial process for generating energy in cells.
Is metabolic activity a direct method to measure growth?
Metabolic activity can be used as an indicator of cellular growth, but it is not a direct method of measuring growth. Metabolic activity refers to the chemical processes that occur within cells, which can be influenced by factors such as nutrient availability and cell division. Growth is typically measured by changes in cell number or size.
What is useful for viewing metabolic activity?
Tools such as positron emission tomography (PET) scans and fluorodeoxyglucose (FDG) tracer can be useful for viewing metabolic activity in the body. These methods involve measuring the uptake of glucose, a marker of metabolic activity, in different tissues. PET scans can provide valuable information about the functioning of organs and tissues in the body.
How do you calculate the metabolic equivalent (MET) for a specific physical activity?
To calculate the metabolic equivalent (MET) for a specific physical activity, you divide the rate of energy expenditure during the activity by the rate of energy expenditure at rest. This gives you a numerical value that represents the intensity of the activity in relation to resting metabolism.
What are three components of energy expenditure?
1. Resting metabolic rate (RMR) or basal metabolic rate (BMR), which equals sleeping metabolic rate (SMR) and arousal. 2. The thermogenic effect of food. 3. Exercise, or daily physical activity and spontaneous physical activity (SPA).
When a doctor says there is no metabolic cancer activity....does that mean the cancer is in remission?
yes
How insulin control the rate of metabolic activity?
Absorptive state imediately following a meal.
What is meant by metabolic activities in cell?
Metabolism refers to the rate at which chemical reactions are synthesised in the body.
