What is defined as the chemical reactions that break down food molecules in cells to release energy? excretion respiration nutrition movement

What do urea, enzymes and ammonia all have in common? they are all proteins O phosphorous they are all essential nutrients nitrogen

Which of the following is NOT true about enzymes?   Enzymes are proteins   Enzymes raise the activation energy of a chemical reaction   Enzymes help a chemical reaction to occur more quickly   Enzymes have an active site   Enzymes may be controlled by feedback inhibition

ATP is a compound that is formed when O O O digestive enzymes break amino acids into smaller parts. energy stored in chemical bonds is released during cellular respiration. chemical bonds between carbon atoms are formed during photosynthesis. energy stored in nitrogen is released, forming amino acids.

Which of the following does NOT describe enzymes? have primary, secondary, tertiary, and sometimes quaternary structure can increase the rate of chemical reactions contain molecules that have amino and carboxyl groups are chemically changed during their participation in chemical reactions subunits are joined by peptide bonds

A B Molecule Energy Released Glucose D Sucrose Lipid If you ate a spoonful of peanut butter for breakfast, the majority of the energy would come from the because it Protein carbohydrate; contains a low ratio of oxygen atoms. sugar, contains high ratio of oxygen atoms. protein; contains nitrogen in place of oxygen atoms. 4 kcal/gram 4 kcal/gram 9 kcal/gram 4 kcal/gram fat, contains a low ratio of oxygen atoms. in the peanut butter

Which statement does not describe an enzyme? enzymes are used up (consumed) by a reaction in biological systems, enzymes are typically proteins enzymes catalyze reactions enzymes help make and break bonds between molecules all of the statements are true

we get energy from food to do what we need to every day. why is digesting food a chemical change?

We should all know that a calorie is the measure of energy required to raise 1 g of water by 1°C. We all know that energy off our food is measured in Calories and that to lose weight we just need to use more than we take in. So how come this isn't a good strategy for weight loss: drink cold water. For every degree you heat up each gram, you'll burn a calorie. If a pound of fat is 3500 Calories, just drink 3500 g of water (3.5 liters) and for every degree it gets warmer in the stomach, you lose a pound.  ?
